Exercise 40 Page 568

If we draw a vertical line between the two figures, it appears that WVZYX is a reflection of PQRST.

By undoing the reflection of WVZYX, we can more easily match the corresponding sides and angles.

Now we can relate the polygons sides and angles.

Corresponding Sides	Corresponding Angles
PQ & WV	∠ R & ∠ Z
QR & VZ	∠ S & ∠ Y
RS & ZY	∠ T & ∠ X
YX & ST	∠ P & ∠ W
TP & XW	∠ Q & ∠ V
