Question

Which postulate or theorem proves ∆WXY ≅ ∆WZY ?


SSS Congruence Theorem


SAS Congruence Postulate


HL Congruence Theorem

Answer 1

Answer:

HL Congruence Theorem

Step-by-step explanation:

Answer 2

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.
