Exercise 35 Page 461

Focus on the triangles △ WZU and △ YZU.

WU>YU

Practice makes perfect

Let's highlight the segments we are asked to compare.

Let's summarize what we know about triangles △ ZWU and △ ZYU.

Claim	Justification
ZW≅ZY	Both of these segments have a measure of 6.
m∠ WZU> m∠ YZU	55>45

Since ZU is a common side, triangles △ ZWU and △ ZYU have two pairs of congruent sides. This means that we can apply the Hinge Theorem. m∠ WZU> m∠ YZU ⇓ WU> YU
