Here in triangle ABD and ACD, AB = AC AD = AD common and we know that in isosceles triangle perpendicular bisec the side BC so BD = CD So  △ABD≅△ ACD, SSS congruencyHence ∠B=∠CRegards

ABC is an isosceles triangle with AB=AC. AD is perpendicular of angle BAC prove angle B =angle C by congruence rule. class 7 congruence of triangles
