Answer 1

Triangle PQR ~ triangle PꞌꞌQꞌꞌRꞌꞌ.

Which two transformations were performed on triangle PQR to produce triangle PꞌꞌQꞌꞌRꞌꞌ?

Choose exactly two answers that are correct.



A.
Triangle PQR was reflected across the y-axis to produce triangle PꞌQꞌRꞌ.

B.
Triangle PQR was reflected across the x-axis to produce triangle PꞌQꞌRꞌ.

C.
Triangle PꞌQꞌRꞌ was dilated by a scale factor of 1/2 to produce triangle PꞌꞌQꞌꞌRꞌꞌ.

D.
Triangle PꞌQꞌRꞌ was dilated by a scale factor of 2 to produce triangle PꞌꞌQꞌꞌRꞌꞌ.

Answer 2

Okay, so it wants two things..a reflection and a dilation.

Answer 3

If the dilation is less than 1, it gets smaller. If it's more than 1 it gets bigger.

Answer 4

Does PQR get bigger when we change it?

Answer 5

Yes. So D, right?
