# What does an isosceles triangle look like?

Triangles are three-sided enclosed polygons and they are classified as equilateral, isosceles, or scalene, based on the length of their sides.

## Answer: In a triangle, if any two sides are of equal length, it is considered to be an isosceles triangle.

Let us understand how does an isosceles triangle looks like.

**Explanation:**

Isosceles triangles are those triangles that have two sides of equal measure, while the third one is of different measure.

- In an isosceles triangle, the altitude from the apex angle (perpendicular) bisects the base and the apex angle.
- The base angles of an isosceles triangle measure the same.
- In a right isosceles triangle, the equal sides form the right angle. In other words, any triangle with angles as 90°, 45°, 45° is a right isosceles triangle.
