Question

. If triangle ABC is isosceles triangle then the base angle cannot be equal to 95 degree let the base angle A are 95 degree in ABC solution

Answer 1

Answer:

So the two base angles must add up to 180-40, or 140°. Since the two base angles are congruent (same measure), they are each 70°. If we are given a base angle of say 45°, we know the base angles are congruent (same measure) and the interior angles of any triangle always add to 180°.
