Hi Okay Assalamualaikum warahmatullahi
0:01
wabarakatuh meet again with
0:04
our channel great mathematics well in our video
0:07
this time we will try to discuss the
0:09
material that is about reflection or
0:11
mirroring that is about how
0:14
to determine the shadow of a point this
0:16
is a mathematics material for kindergarten junior high school
0:19
and also mathematics material for
0:21
high school level can before we continue don't
0:24
forget to like subscribe comment and share
0:26
our video hopefully the video is useful
0:28
and hopefully it can be a charity
0:31
for us later and now let
0:34
's just discuss the example questions
0:37
but before that it's good for us to
0:39
understand first some
0:41
important materials to make it easier for us to
0:44
answer questions about this reflection,
0:46
namely as follows we have
0:49
summarized it into a table form
0:51
usually here there is a form of a
0:53
reflection okay then we are given a
0:57
point usually kebab then
1:00
Khan the point is on the right side of this
1:03
Well to make it easier for us to
1:06
understand the summary of this material let's just
1:08
discuss the example questions Determine
1:14
the shadow of the point if the first question
1:16
finding a 3.5 is reflected on the
1:19
x-axis the second question point B 4.2
1:24
is reflected on the y-axis the
1:28
third question point c 2.375 is reflected
1:31
to the origin 0,0 and so on
1:34
this time we have 7 Make a question and that
1:39
God willing we will answer one by one
1:41
until you can later now
1:45
let's start to discuss the
1:47
first question first the point
1:52
advrcntr3.dll x-axis pay attention to the
1:55
steps in this work it is very
1:57
easy remember once again
2:00
To make it easier for us to answer
2:02
questions about reflection of course you
2:04
have to really understand the material that
2:07
has been camera kuntadi in the form of a
2:09
table earlier Well here it is if we have
2:12
mastered this God willing
2:15
we can easily answer questions about reflection
2:18
earlier no for the first one we
2:22
were given a point a 3,5 then
2:26
reflected on the x-axis
2:29
Pay attention to the table here reflection on the
2:31
x-axis if for example we are given a
2:34
point a comma b then the shape of the shadow of
2:38
the point is a woman FB the front number
2:43
remains the root behind it is associated with
2:46
negative previously positive b then it
2:52
Oh so it is with this time then the
2:55
shape of the shadow after being reflected
2:58
on the x-axis becomes a accent
3:00
in brackets once again Pay attention to the
3:03
front number remains a-rank kablak
3:07
gangnya multiplied by negative previously
3:09
positive B then the shadow changes to
3:12
negative B well so it is with The
3:15
front id point remains 3.4 Now the
3:21
last number changes to negative, it was
3:24
positive before, where now it changes
3:26
to negative 5 Now this is the correct answer
3:30
to our first question
3:33
Yes, it's not very easy
3:35
of course Ok, continue he understands better
3:37
Now we will go into the second river,
3:40
pay attention to the second point B 4.2
3:43
reflected on the y-axis, here are the
3:47
display steps, point B
3:51
4.2 is negative two, then it is reflected
3:55
on the y-axis, pay attention to the reflection of
3:57
your y-axis, we are like this, point a
4:01
comma b, then the shape of the shadow after
4:04
being reflected on the y-axis is there, it
4:05
becomes negative A5B, the front number
4:11
is multiplied by negative, the
4:13
back number here he still pays attention to
4:16
the shadow of point B, this B accent, the
4:21
front number is multiplied by negative once
4:23
again, Pay attention to the front number multiplied
4:25
by negative, it was positive exactly
4:28
multiplied by negative, it becomes negative 4, now the
4:33
Srikandi here, but then here
4:36
it is also negative two Now this is the
4:39
correct answer to our
4:41
second question, it is very easy, you certainly continue
4:44
he understands better, we go into the third question,
4:47
point c 2.5 is reflected
4:51
on the origin 0.0 three Our point is
4:57
at 2.375 then it is reflected to the
5:01
origin point note the reflection of the
5:04
origin point 0.0 if we are given a point a
5:07
comma b then the shape of the shadow is
5:11
negative acoma negative all these number points
5:14
are associated with a negative sign
5:16
previously positive-positive b then the shape of
5:19
the shadow is negative negative B
5:23
likewise Relax the third woman is point
5:25
c then the shape of the shadow is C accent
5:29
remember all the numbers here are multiplied
5:33
Hi then the shape of the number pay attention
5:35
once again positive 2 then the shadow is
5:39
negative two then comma previously negative 5
5:42
then right the service here is
5:45
positive 5 remember all the numbers here
5:47
are multiplied by a negative sign positive 2
5:51
times negative becomes negative 2 negative
5:53
5 in you multiplied by negative the
5:56
result is positive this is the
5:59
answer form of the third example dear continue
6:04
again so that we really understand we
6:05
enter the fourth question negative meet point
6:08
7.2 is reflected to the line
6:11
y = x okay pay attention to point D negative 7.2
6:17
is reflected to the line y = x
6:19
reflection of the line y = x if we are given a
6:25
point a comma b then the shape of the shadow
6:33
just swap the position previously AB then the
6:37
shape the danger of customs Likewise with the
6:41
point at us this time the
6:43
shadow form is the absent which
6:47
was previously negative 7.2 then the
6:49
shadow form gives it now it is
6:52
2.5 egat yv7 well this is how
6:57
to reach the 4th very easy
6:59
of course Ok continue he understands better
7:02
now we go into the fifth like
7:05
point e 5.4 is reflected on the line
7:08
y is equal to negative X make sure point e
7:14
So 5.45 lu is reflected on the
7:17
line y = x line y = min x if we
7:24
are blessed with point a comma b then the
7:27
shadow form is negative become negative
7:33
Mbok Ade she swapped positions means that
7:36
previously it was finished now it changed to customs Then
7:38
after that it was multiplied by the
7:40
negative sign previously positive AB now
7:43
it changed to negative B negative a & b that is
7:48
also with the TNI point according to the fifth
7:50
shadow form after being reflected
7:53
on the line y = min x namely the number of
7:56
X accents in brackets starting from the first he
8:00
swapped positions previously 54 now it changed
8:04
to 45 after that it was multiplied by the
8:08
negative sign so now it becomes
8:11
replaced by V4 okay comma negative 5 Well this is the
8:18
correct answer from Our question
8:19
number five continues now we go to the
8:24
other six points f 2.33 reflected
8:33
brother the solution steps mix
8:35
point FT at 2.33 then reflected
8:40
reflect on the line x = 3
8:44
this calf x = h if we are near point a comma
8:49
b then the shape of the shadow is the
8:53
front number note for the slightly different
8:55
Club it changes to 2H minus a
9:00
if HK the value of our hadith al this time
9:03
is three Yes the dream is still okay Tadika
9:10
then the shape of the shadow is F accent
9:14
in brackets the front number note the
9:17
change this front number is two [ __ ]
9:20
minus a-ha this if we can this time
9:24
three steps so it is two when
9:27
the package is twice Abadi 2 times three
9:33
Hi this current value is like this laiya
9:35
here we are two batti2 times three which is here
9:39
subtracted by two which is here comma
9:44
then the purchase number make sure he remains
9:47
this calf he remains negative 3 continue F
9:53
accent in brackets two times three the
9:56
result is 6 then 6 minus 2 the result is
10:00
4.3 the back is still negative 3
10:03
Well this is the answer to
10:06
our last sixth question This is
10:10
the last question number 7
10:12
negative Gis point 1.7 is reflected on the
10:16
line y = 4 but make sure the height of
10:20
negative 1 point seven is reflected
10:24
on the line y = 4 line y = if
10:29
for our formula this time pay attention to
10:33
Hi if for example we are blessed with point
10:35
a comma b then the shape of the shadow
10:39
pay attention to A5 the front number remains Aa
10:42
then the back number changes previously
10:45
by now changes to two chalk b & k
10:49
here for our prayer this time that is
10:52
the value 4D pay attention to the shadow gi
10:56
then the shadow is G accent will be
11:00
in front once again Pay attention to the
11:02
front number remains if here the
11:04
front number is negative one then the
11:08
back number just changes previously B
11:10
now changes to two less b
11:13
the value of this Village Head is four so pay
11:17
attention once again two here okay
11:20
I multiplied by four here
11:24
then described with BB Here in
11:26
others 7 George in ASEAN in brackets
11:33
Mbak comma 2 times 4 only eight then
11:37
8067 the result is one and this is
11:41
how to solve questions
11:43
about reflection or shadow of a
11:46
point that's our short tutorial
11:49
hopefully the video is useful More and
11:51
less we apologize we close with Peace be
11:53
upon you, and Allah's mercy and blessings
