Answer 1

Triangle ABC is similar to triangle AꞌꞌBꞌꞌCꞌꞌ.

Which transformations were performed on triangle ABC to produce triangle AꞌꞌBꞌꞌCꞌꞌ? All dilations have a center of dilation at the origin and all rotations are around the origin.



A.
Triangle ABC was reflected across the x-axis and then dilated by a scale factor of 2 to form triangle AꞌꞌBꞌꞌCꞌꞌ.

B.
Triangle ABC was dilated by a scale factor of 2 and then rotated 90° counterclockwise to form triangle AꞌꞌBꞌꞌCꞌꞌ.

C.
Triangle ABC was reflected across the y-axis and then rotated 180° clockwise to form triangle AꞌꞌBꞌꞌCꞌꞌ.

D.
Triangle ABC was dilated by a scale factor of 2 and then reflected across the y-axis to form triangle AꞌꞌBꞌꞌCꞌꞌ.

Answer 2

Any picture?

Answer 3

Trying to load it but it wont pop up to select the picture

Answer 4

Okay, well it says "Triangle ABC is SIMILAR to A"B"C""

That means we cannot just reflect it

Answer 5

i wana say since it crossed the x axis and then was dialated by 2

Answer 6

it would be one of the following answers that have reflcection over x

Answer 7

Bingo.

Answer 8

as i said reflect over x and divi by 2

Answer 9

do u get it ?

Answer 10

Okay, what do you think is correct?

Answer 11

Answer 17

yes

Answer 18

Answer 21

the reflection is larger.

Answer 22
