In an isosceles triangle, two sides are equal and their opposite angles are also equal. Then the correct option is D.
What is the triangle?
A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
An isosceles triangle includes two 72° angles.
In an isosceles triangle, two sides are equal and their opposite angles are also equal.
And the sum of the angles of the triangle is 180°.
Let the third angle be x. Then we have
72° + 72° + x = 180°
180° - 2(72°) = x
Thus, the correct option is D.
