Isosceles & Equilateral Triangle

In geometry, Isosceles and equilateral triangle play an important role. Isosceles triangle means that it has two congruent sides. Often it is mentioned by the measurement of one side is identical by the other side of the triangle. Typically is two sides are marked that also means that are congruent or equal length. The third side is not mathematics marked means it is not same like the other two. Equilateral triangle is when all three sides are congruent. Also when all three sides are marked, an equilateral triangle can be drawn one way, noticing that the each of the angles is acute.

The key concept here is number congruent sides. The number congruent sides always tell us how many congruent angles we have. In Isosceles triangle if there are two congruent sides then there will be two congruent angles. Where as in equilateral triangle all the three sides are congruent thus will have all three congruent angles. In isosceles triangle where two sides are marked congruent. Here the base of the side is not congruent to the other two or not equal length of the other two sides. The base angles are congruent for an isosceles triangle.

The congruent sides are always opposite to the congruent angles in isosceles triangle. For equilateral triangles, the angles are opposites are congruent in all the three sides. As all three sides are congruent, that means all three angles are also congruent. So if we consider that the sum of all the angles is 180 degrees, and all three angles are congruent .simple divide it by 3 will give us 60 degrees each. No matter how big or small the triangle is drawn. Thus stated that equilateral triangle can only be drawn one way. Thus we understand that there are differences between isosceles and equilateral.
