### What is Meant by Isosceles Trapezoid?

In Maths, Isosceles trapezoid (also known as isosceles trapezium) is defined as a convex quadrilateral, which consists of a line of symmetry that bisects one pair of the opposite side. In an isosceles trapezoid, the base angles are of equal measure. It has parallel bases and also the legs are of equal measure. The opposite angles of the isosceles trapezoid are supplementary, which makes it a cyclic quadrilateral. The area of the isosceles trapezoid is the average of the base length times the height. If “a” and “b” are the bases and “h” is the height, then the area is calculated as follows:

Area of an Isosceles Trapezoid = [(a+b)h]/2 square units

For example, the bases of the isosceles trapezoid are 2 cm, and 5 cm and height is 5cm, then the area is:

Area = [(2+4)5]/2

Area = 30/2

Area = 15 cm2.

Hence, the area of an isosceles triangle is 15 cm2.
