An isosceles triangle with legs measuring 10 in and a vertex angle of 30 degrees.

Isosceles triangle is a triangle which has at least two of it's sides equal to each other.

Explanation:

In geometry, an isosceles triangle is a triangle that has two sides of equivalent length. Here and there it is determined as having precisely different sides of equivalent length, and at times as having at any rate different sides of equivalent length, the last form subsequently including the symmetrical triangle as an extraordinary case.

An isosceles triangle is a triangle with (in any event) two equivalent sides. In the figure over, the two equivalent sides have length and the staying side has length. This property is equal to two points of the triangle being equivalent.
