Introduction:
In this article let me help you on equilateral triangle. An equilateral triangle is an one triangle in which all three sides and angles are equal. In Euclidean or traditional geometry, equilateral triangles are equiangular; that is, all three internal angles are also congruent to each other and also each are 60°. They are regular polygons, and can therefore also be called to as regular triangles.
An equilateral triangle is the symmetrical triangle, having 3 lines of rotational and reflection symmetry of order 3 about its center.
A regular tetrahedron is made up of four equilateral triangles.This could also help us on prime numbers up to 100.
Examples
Example 1:
To find the area of the equilateral triangle with side length 5 cm.
Area=a2 ( √ 3)/4
=52(1.732)/4
=43.3/4
=10.825cm2
