The height of an isosceles triangle divides it into two right-angled triangles. The other dimensions of the triangle like altitude, area, the perimeter can be calculated by using the simple formulas mentioned below.Īltitude is a line drawn from one vertex of the triangle to the midpoint of its opposite side. The two equal sides are called the legs and the third side is called the base of the triangle. In some cases, it has exactly two sides of equal length and otherwise having at least two sides of equal length. Isosceles Triangle is a triangle that has two sides of equal length.
