An isosceles right triangle is a triangle with 2 congruent sides and angles in which the non-congruent angle measures 90°. Because the sum of a triangle's interior angles is equal to 180°, the remaining two angles in an isosceles right triangle measure 45° (90 + 45 + 45 = 180°).

What is an isosceles triangle? An isosceles triangle is a triangle with two sides of equal length, called legs. The third side of the triangle is called the base. The vertex angle is the angle between the legs. The angles with the base as one of their sides are called the base angles.

Triangles - Equilateral, Isosceles and Scalene
A triangle has three sides and three angles. The three angles always add to 180°. There are three special names given to triangles that tell how...

Isosceles Triangle - GeeksforGeeks
An isosceles triangle will always have at least two equal sides and two equal angles. In an isosceles triangle, the two sides of equal length are called the legs, and the third side of the triangle is called the base.

Isosceles Triangle - Properties | Definition | Meaning | Examples
An isosceles triangle is a triangle in which at least two sides are equal. Following this fact, if two sides of a triangle are equal, then the angles opposite to those sides are also equal.

Isosceles Triangle -- from Wolfram MathWorld
A triangle with all sides equal is called an equilateral triangle, and a triangle with no sides equal is called a scalene triangle. An equilateral triangle is therefore a special case of an isosceles triangle having not just two, but all three sides and angles equal.
