Area of an isosceles triangle formula
A = (1/2) × b × h
- where b is the base and
- h is the height of the triangle.
In an isosceles triangle, the base is equal to the length of each of the equal sides, and the height is a line perpendicular to the base that passes through the midpoint of the base and intersects the equal sides.
To find the area of an isosceles triangle, we need to know the length of the equal sides and the height. Once we have these measurements, we can substitute them into the formula to find the area.
