Step-by-step explanation:
In triangle XBZ AND CYZ ,
BZ = CZ -------- z is the midpoint
angleXBZ=angleYCZ. ------- both angles are 90°
BX =CY --------- Height of ∆ABC
so, by SAS congruency test ,
∆XBZ=∆YCZ
Therefore, by CPCT, XZ=YZ

Step-by-step explanation:
triangles XBZ and YCZ are congruent by SAS
BX=YC
angle XBZ= angleYCZ
BZ=ZC
so by cpct
XZ=ZY
