Answer #1

We do this by contradiction...

Given that two angles of traingle are not congruent...

Let us assume that their opposite two side of a triangle are congruent..

So triangle is issoceles triangles...and in issoceles traingle two angles are congruent...or you can use theoram.

Theoram states that , opposite angle of congruent sides are congruent...

So two angles of triangle are congruent... But it is contradiction to given statement...

So our assumption is wrong..

This shows that these two opposite sides of those angles are not congruent..

Any doubt then comment below..

If the parts of two triangles are matched so that two angles of one triangle are congruent to the corresponding angles of the other, and so that a side of one triangle is congruent to the corresponding side of the other, then the triangles must be congruent. Justify this angleangle-corresponding side (AAS) criterion for congruence. Would AAS be a valid test for congruence if the word corresponding were left out of the definition? Explain.
