One of the angles of an isosceles triangle is . What is the measure of the other two angles?
Step I - As one of the isosceles triangle is .
So, other two angles must be equal to each other because two opposite angles are equal to opposite equal sides.
Step II - Let other two angles be .
As we know that sum of the angles of the triangle is .
Then,
Hence, other two angles are of isosceles triangle are .
