The two base angles and the vertex angle are all acute. In this type, all three interior angles are acute angles, which means they are less than 90 degrees. Here are the main types of isosceles triangles: Isosceles triangles can be categorized into different types based on their unique properties. The line drawn from the vertex angle to the midpoint of the base bisects the triangle into two congruent right triangles.The angle opposite the base in an isosceles triangle is generally larger than the base angles.This property is a direct consequence of the equal side lengths. An isosceles triangle always has congruent angles at the base.Two congruent sides are the most defining characteristic of an isosceles triangle.Here are some notable characteristics of isosceles triangles: Isosceles triangles possess particular characteristics that distinguish them from other types of triangles. Useful Properties of an Isosceles Triangles The congruent angles are always opposite the sides that have the same length.

Therefore, an isosceles triangle has two congruent and one different angle. The angles opposing the legs have the equal measurement. These two sides are known as the legs of the triangle and the third side is referred to as the base. Definition of Isosceles TriangleĪn isosceles triangle is a particular type of triangle in which two sides have an equal length. We will dive deep into the world of isosceles triangles, exploring their properties, types, and many examples. We will confine ourselves to only the isosceles triangle in this blog. The triangle has three types based on its sides in Geometry, such as: Therefore, an isosceles triangle is defined by having two sides of the same length, which are often called legs, and a third side called the base, which is either longer or distinct from the legs. The word isosceles originates from Greek words isos meaning equal, and skelos, meaning leg. Triangles with at least two equal sides are referred to as isosceles triangles.
