The Δ FGH with base FG that is 2a unit long has been drawn below.
A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
Δ FGH is a isosceles triangle.
Now isosceles triangle is a triangle whose two sides are equal.
