In an isosceles triangle that has exactly two equal sides, the equal sides are called legs and the third side is called the base. The angle included by the legs is called the vertex angle and the angles that have the base as one of their sides are called the base angles.
Isosceles triangle is a triangle in which two sides are of equal length and two angles are of equal measure. Scalene triangle is a triangle which has all sides of different length and all angles are of different measure. Now we will see how many angles does a triangle have. As we know that a triangle has 3 sides and 3 vertices and each vertex has one angle in them and therefore there are total of 3 angles in a triangle.
