Question

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.

Answer 1

Answer 4

ok first of all what do u think

Answer 5

I think D

Answer 6

try again the y axis is the vertical one

Answer 7

@welshfella

Answer 8

it crossed the x axis and then was dialated by 2

Answer 9

So either A or D?

Answer 10

a

Answer 11

Thank you

Answer 12

yes a is correct
