G.SRT.1, G.SRT.2, and G.SRT.3 - Similarity Transformations

Which transformation maps triangle PQR to triangle P'Q'R'?

A dilation about the origin with scale factor k=4 is applied to the following line

Use the coordinates in the image below to decide whether the triangles are similar by a similarity transformation.

Triangle T is mapped to triangle T' by a rotation about the origin followed by a dilation centered at the origin by 180°.

Triangle A'B'C' is the image of triangle ABC under a dilation with an unknown center and scale factor k>0.

Select all evidence that supports the claim triangle A'B'C' is similar to triangle ABC.
