Answer 1

Step-by-step explanation:

Given; an isosceles triangle ABC with AB=AC

To prove: angle A=angle C

construction: draw the angle bisector AD of angle A

Consider ∆ABD & ∆ACD

AB=AC (given)

AD = AD ( common)

angle BAD = angle CAD( AD is the angle bisector)

therefore,by SAS congruency,

∆ABD is congruent to ∆ACD

therefore,by CPCT , angleB = angleC
