Question

Which transformations will produce similar, but not congruent, figures?

A.
Triangle PQR is reflected across the x-axis and then rotated 90° clockwise to form triangle PꞌꞌQꞌꞌRꞌꞌ.

B.
Triangle PQR is reflected across the y-axis and then dilated by a scale factor of 6 to form triangle PꞌꞌQꞌꞌRꞌꞌ.

C.
Triangle PQR is rotated 180° counterclockwise and then translated 11 units left to form triangle PꞌꞌQꞌꞌRꞌꞌ.

D.
Triangle PQR is rotated 90° clockwise and then reflected across the y-axis to form triangle PꞌꞌQꞌꞌRꞌꞌ.

Answer 1

I think it's A.

Answer 2

okay what do you think @automaticloveletter

Answer 3

i think it's A.

Answer 4

It would be B. Dilation means changing the size, therefore they would be similar but not congruent.

Answer 5

okay thanks guys

Answer 6

You're welcome (:

Answer 7

Triangles are congruent when they have exactly the same three sides and exactly the same three angles. So what do you think?
