∆ABC and ∆PQR are similar. ∆ABC is dilated by a scale factor of 1.25 and rotated 45° counterclockwise about point B to form ∆PQR. The side lengths of ∆ABC are AB¯¯¯¯¯, 5 units; BC¯¯¯¯¯, 4.2 units; and AC¯¯¯¯¯, 4 units. Match each side of ∆PQR to its length.

    This is quite simple one you understand it. All you have to do is multiply 5,4.2, and 4 by 1.25

    seperate. So 5 x 1.25, 4.2 x 1.25, then 4 x 1.25

    Yes, it does. So I just multiply those by 1.25 and that's the answer?

    the triangles are similar so pq is = to ab, qr is = to bc, and ac is = to pr
