WebHere is a list of a few properties of isosceles triangles: An isosceles triangle has two equal sides and two equal angles. The two equal sides of an isosceles triangle are called the legs and the angle between them is called the vertex angle or apex angle. The side opposite the vertex angle is called the base and base angles are equal.

WebSo 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°.
