Triangles can be of three types depending on the length of each side:-

1. Equilateral triangle- When each of the sides of a triangle is of equal length, it is called an equilateral triangle.
2. Isosceles triangle- If any two sides of a triangle are equal, then it is termed as an isosceles triangle.
3. Scalene triangle- If all the sides of a triangle are of different length, then it is a scalene triangle.
