![]() ![]() The area of an isosceles triangle refers to the total space covered by the shape in 2-D. What is the Formula for Area of Isosceles Triangle? The perpendicular from the vertex angle bisects the base and it also bisects the vertex angle.The side opposite the vertex angle is called the base and base angles are equal.The two equal sides of an isosceles triangle are called the legs and the angle between them is called the vertex angle or apex angle.Here are some properties of an Isosceles triangle that distinguish it from other types of triangles: What is an Isosceles Triangle?Īn isosceles triangle is defined as a triangle having two sides equal, which also means two equal angles. Thus, the area of an isosceles triangle means the total space enclosed by an isosceles triangle. The area of a figure is the region enclosed by the figure. ⇒ Area = (a + b/2 − a) × √Īrea of isosceles triangle = b/2 × √(a 2 − b 2/4) square unitsįAQs on Area of an Isosceles Triangle What Does the Area of an Isosceles Triangle Mean? Here, s is half of the perimeter of the triangle, and hence, it is called semi-perimeter. We know that the perimeter of a triangle with sides a, b, and c is a + b + c. s is the semi perimeter of the triangle.a, b, and c are the sides of the triangle.The Heron's formula to find the area, A of a triangle whose sides are a,b, and c is: Heron's formula is used to find the area of a triangle when the measurements of its 3 sides are given. The area of an isosceles triangle formula can be easily derived using Heron’s formula as explained in the following steps. β = measure of the angle opposite to the base.α = measure of equal angles of the isosceles triangle. ![]()
