EQUILATERAL TRIANGLE #equilateral #triangle
Equilateral Triangle : A triangle in which all the sides are of equal length then the triangle is called an equilateral triangle.
Since the lengths of the sides of equilateral triangle are equal, the angles oppose to the side are also equal.
Hence an equilateral triangle is also called an equiangular triangle.
Also since the sum of angles in a triangle is 180 and since the angle in the equilateral triangle is same, each angle in the equilateral triangle is 60.
Area of equilateral triangle is given by A(area) = √3/4 x a^2, where a is the length of the each side.
Construction of equilateral triangle :
step 1. Draw a straight line AB.
step 2. Set the compass to the length AB.
step 3. Using straightedge draw an arc above AB by considering A as center.
step 4. Again draw an arc above AB by considering B as center.
step 5. Label the point as C where the arcs are intersect.
step 6. Join A to C and B to C , then we get our required equilateral triangle .
