how to find the area of an isosceles triangle

Isosceles triangle calculator

This calculator calculates any isosceles triangle specified by two of its properties. An isosceles triangle is a triangle that has two sides of equal length. Our calculator provides the calculation of all parameters of the isosceles triangle if you enter two of its parameters, e.g. base b and an arm a. It is not a problem to calculate an isosceles triangle, for example, from its area and perimeter (T=12 p=16).

Examples of calculating isosceles triangles:

angle α and base c
base c and arm a
height and arm a
area S and angle γ

An isosceles triangle in word problems in mathematics:

Isosceles - isosceles
