Triangle ABC is transformed to obtain triangle A′B′C′:



Which statement is correct for and ?
A , because is obtained by dilating by a scale factor of and then rotating it about the origin by 90 degrees
B, because is obtained by dilating by a scale factor of and then rotating it about the origin by 180 degrees
C, because is obtained by dilating by a scale factor of and then rotating it about the origin by 180 degrees
D, because is obtained by dilating by a scale factor of and then rotating it about the origin by 90 degrees

Answer 1

plz help

Answer 3

any ideas

Answer 4

Could I help you?

Answer 5

yes

Answer 6

that would be great

Answer 7

That is with my pleasure!

Answer 8

Let
s agree firstly that the triangle is dilated by a scale factor then it rotates!
ok?

Answer 9

ok

Answer 10

what is the difference between A and D?

Answer 11

its 90

Answer 12

degree

Answer 13

I mean A is the same as D, how is that?

Answer 14

no

Answer 15

so what is the difference?

Answer 16

the 1/3

Answer 17

and 1/6

Answer 18

no numbers are encountered

Answer 19

A , because is obtained by dilating by a scale factor of and then rotating it about the origin by 90 degrees
B, because is obtained by dilating by a scale factor of and then rotating it about the origin by 180 degrees
C, because is obtained by dilating by a scale factor of and then rotating it about the origin by 180 degrees
D, because is obtained by dilating by a scale factor of and then rotating it about the origin by 90 degrees

Answer 20

oh ok

Answer 21

Okay, so you see triangle ABC, and A'B'C' - Triangle A'B'C' is just a reflection of ABC across the Y axis, and the labeled points are correlating with each other, meaning
A = A'
B = B'
C = C'
When I say that the points correlate with each other, I mean that they are practically the same point, just on another triangle. Think of it like point A' is the twin of point A.

Answer 22

Now, with that being said, since the points correlate with each other, so do their angles. So, look at your answer choices again and tell me if you can spot any correlating angles

Answer 23

oh

Answer 24

i think its B
