∆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

OpenStudy (baseballguy101):

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

OpenStudy (baseballguy101):

does it make sense why?

OpenStudy (anonymous):

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

OpenStudy (baseballguy101):

yep let me see what you got when you're done

OpenStudy (anonymous):

But the angles down below do not make sense?

OpenStudy (baseballguy101):

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

OpenStudy (anonymous):

OH.

OpenStudy (anonymous):

I feel dumb, lol.

OpenStudy (anonymous):

Here, I think I got it?

OpenStudy (baseballguy101):

haha don't . And yes that's correct
