Answer:

HL congruence theorem

Step-by-step explanation:

Given that WZX is an isosceles triangle with sides WX=WZ

Also given that WY is altitude on side XZ

Consider triangles WXY and WZY

WX=WZ             Given

WY=WY             REflexive property

Angle wyz =angle wyx     Right angle

Hence by HL congruence theorem, since one leg and hypotenuse are equal we get the two triangles to be congruent.
