Step-by-step explanation:
Types of Triangles
A triangle can be classified by either its sides: or its angle.
(A) A triangle is classified in three types as scalene, isosceles, or equilateral triangle based on its sides.
1. Equilateral triangle
A triangle having all sides equal is called an equilateral triangle. It’s all angles are also equal. As sum of three angles of a triangle is 180°, so each angle of an equilateral triangle is 60°.

2. Isosceles triangle
A triangle having two sides equal is called an isosceles triangle. The angles opposite to equal sides are also equal.

3. Scalene triangle
A triangle having all sides of different length is called scalene triangle.

In the figure above, the sides a≠ b≠ c . Hence this is a scalene triangle.
