Area of Isosceles Triangle

An isosceles triangle has two equal sides and the angles opposite these equal sides are also equal.

Area of Isosceles Triangle Formula :

A = ¼ × b√(4a2 – b2)

where, a = both the equal sides

and b= the third unequal side

Area of Triangle | Formula and Examples

Area of a triangle is the region enclosed by all its three sides. It is generally calculated with the help of its base and height. To Find the Area of a triangle A with base b and height h, We use the formula, A = [Tex]\frac{1}{2} \times b \times h [/Tex].

Let’s learn about the area formulas for different types of triangles in detail, with the help of solved examples.
