Question

IF triangle ABC and triangle PQR are similar triangles, find QR and PR

QR=
PR=

Answer 1

Since the triangles are similar, corresponding sides have proportional lengths.
First, you need to find a pair of sides, one side in triangle ABC and one side in triangle PQR, that are corresponding sides and that you know both lengths.

Answer 2

Can you name such a pair of sides?

Answer 3

IDK

Answer 4
