isosceles
All triangles have three angles.
To find the equal angels, base angles, of an isosceles triangle and you know the vertex angle, 180-vertex angle and then divide by two.
In a isosceles triangle, all angles are less than 90 degrees and therefore they are acute angles. Two angles on the opposite side of each other are equal angles.
The three angles of a triangle is as a result of these three types of a triangle: equilateral, isosceles and scalene.

An isosceles triangle.
In a isosceles triangle, all angles are less than 90 degrees and therefore they are acute angles. Two angles on the opposite side of each other are equal angles.

The triangle is an isosceles triangle.
The sum of all the interior angles of any trapezoid is 360 degrees.
An isosceles trapezoid
It is a trapezoid. If the 2 nonparallel sides are congruent, then it is an isosceles trapezoid.
