What is the length of the sides of an isosceles triangle?

The length of the sides of an isosceles triangle are not set in stone. An isosceles triangle is defined as a triangle with at least two congruent sides. Equilateral triangles; that is, triangles in which all sides are of equal length are also considered to be isosceles triangles. Therefore, as long as at least two sides of the triangle are congruent, (Of equal length) said triangle is an isosceles triangle.


Are all sides of an isosceles triangle are congruent?

No because only 2 of its 3 sides are congruent in an isosceles triangle but all 3 sides of an equilateral triangle are congruent.


If it is an equilateral triangle then it is an isosceles triangle?

Let us recall the definition of an isosceles triangle. An isosceles triangle is a triangle with two equal or congruent sides. In this definition, it is not stated that it has exactly two equal sides. An equilateral triangle has three equal or congruent sides. If it has three equal sides, then it must have two equal sides. Therefore, an equilateral triangle is considered as an isosceles triangle. But, an isosceles triangle is not necessarily an equilateral triangle.
