The altitude of a triangle is a perpendicular distance from the base to the topmost.

If the third angle is the right angle, it is called a right isosceles triangle.The base angles of the isosceles triangle are always equal.The unequal side of an isosceles triangle is normally referred to as the base of the triangle.Here, the student will learn the methods to find out the area, altitude, and perimeter of an isosceles triangle. These special properties of the isosceles triangle will help us to calculate its area as well as its altitude with the help of a few pieces of information and formula. Thus in an isosceles triangle to find altitude we have to draw a perpendicular from the vertex which is common to the equal sides.Īlso, in an isosceles triangle, two equal sides will join at the same angle to the base i.e. It is unlike the equilateral triangle because there we can use any vertex to find out the altitude of the triangle.

In this article, we will discuss the isosceles triangle and various isosceles triangle formula. Therefore we may conclude that all equilateral triangles also have all the properties of an isosceles triangle. If all three sides are equal in length then it is known as an equilateral triangle. An isosceles triangle two angles will also be the same in front of the equal sides. The isosceles triangle is a type of triangle, which has two sides with the same length.
