Some points related to a triangle :–

★ It has 3 vertices.

★ It has 3 edges.

★ There are 3 types of triangle :-

1. Equilateral triangle → All the three sides are equal, interior angles = 60°.
2. Isosceles triangle → Two sides are equal and one side is unequal to the both equal sides.
3. Scalene triangle → No sides are equal (All the three sides of a scalene triangle are unequal).

★ Sum of all angles of a triangle is 180°.

★ Area of a triangle = $\sf \dfrac{1}{2} \times Base \: (b) \times Height \: (h)$

★ Perimeter of a triangle = Sum of all the three sides.
