Equilateral Triangle: Types of Triangles Equilateral Triangle: All sides and all angles are equal. Isosceles Triangle: Two sides and two angles are equal.

Right-Angled Triangle: Types of Triangles Right-Angled Triangle: One angle is a right angle (900). The side opposite the right angle is called the Hypotenuse Scalene Triangle: No equal sides and no equal angles.
