## isosceles triangle

### a triangle with at least two congruent sides

An isosceles triangle is a triangle in which two sides are of equal length. This means that two of the angles opposite those sides are also equal. The side that is not equal to the other two is called the base, and the angle opposite the base is known as the base angle. In an isosceles triangle, the base angles are always equal.

There are several properties of isosceles triangles that are worth noting. For example, the altitude from the vertex angle of an isosceles triangle always bisects the base. This means that it divides the base into two equal parts. Additionally, the median from the vertex angle of an isosceles triangle also bisects the base. This means that it divides the base into two equal parts.

Another key property of isosceles triangles is that they can be used to create symmetrical shapes in geometry. For example, two isosceles triangles placed base to base can create a rhombus, while four isosceles triangles can create a square.

Overall, isosceles triangles are an important concept in geometry and have many important applications in mathematics and other fields.
