Area of Isosceles Triangle using Trigonometry
When the Length of the two Sides and the Angle between them are given,
A = ½ × b × c × sin(α)
Where,
- b, c are sides of a given triangle, and
- α is the angle between them.
When the two angles and sides between them are given,
A =
Where,
- c is sides of a given triangle, and
- α, β is the angle associated with them.

Area of an isosceles triangle is the space enclosed by the sides of a triangle. The general formula for finding the area of the isosceles triangle is given by half the product of the base and height of the triangle. Other than this different formulas are used to find the area of triangles. Triangles are classified depending on their sides, different types of triangles based on sides are given below:
Equilateral Triangle: Triangle with all three sides equal.
Isosceles Triangle: Triangle with any two sides equal.
Scalene Triangle: Triangle with all sides unequal.
