Base Angle of Isosceles Triangle Calculator

An Isosceles Triangle has two equal sides and the third unequal side is called as base. The base angles of an isosceles triangle are the two angles with the same measure, each formed by the intersection between the base of the triangle and one of the two legs. Use this online Base angle of Isosceles triangle calculator to find the apex angle with known values of base angle.
