What is an Equilateral Triangle

What is an Equilateral Triangle There are different types of triangles based on the sides and the angles of the triangle, and one such type of a triangle is the Equilateral triangle. An equilateral triangle is a triangle which has all equal sides, which implies all the 3 sides are equal in length. Because the sides are equal, the 3 angles are also equal to each other. Since the sum of all the angles in any triangle must add up to 180, hence each angle in an equilateral triangle measures 60. Example 1: What is the area of an equilateral triangle which has the side length equal to 5m? Given the side of an equilateral triangle, s = 5m An equilateral triangle has all the 3 sides equal to each other in length. Hence all the sides are equal to 5m. Area of an equilateral triangle, A = 3/4 * s2 Area of the equilateral triangle, A = 3/4 * (5m) 2 Area, A = 3/4 * 25 = 10.8m2 Hence area of the given equilateral triangle, A = 10.8m2 Example 2: What is the area of an equilateral triangle which has the side length equal to 6m? Given the side of an equilateral triangle, s = 6m An equilateral triangle has all the 3 sides equal to each other in length. Hence all the sides are equal to 6m. Area of an equilateral triangle, A = 3/4 * s2 Area of the equilateral triangle, A = 3/4 * (6m) 2 Area, A = 3/4 * 36 = 15.6m2 Hence area of the given equilateral triangle, A = 15.6m2
