![]() It is the number of unit squares that can be fit inside the shape and it is measured in square units such as cm 2, m 2, in 2, etc. To find the area of a trapezoid, the lengths of two of its parallel sides is to be known and the distance (height) between them. The area of the trapezoid is calculated by measuring the average of the parallel sides and multiplying it with its height. There are two main trapezoid formulas, they are: In the below right trapezoid or right-angled trapezoid, there are two right angles one at D and the other one at A. These kinds of trapezoids are used to estimate the areas under the curve. DC and AB are parallel to each other but are of different lengths.Ī right trapezoid also called the right-angled trapezoid, has a pair of right angles. AB, BC, CD, and DA are of different lengths. In the below scalene trapezoid, all four sides i.e. When neither the sides nor the angles of the trapezoid are equal, then it is a scalene trapezoid. WX and YZ are called the legs of the trapezoid since they are not parallel to each other. In the below isosceles trapezoid XYZW, XY and WZ are called the bases of the trapezoid. ![]() An isosceles trapezoid has a line of symmetry and both the diagonals are equal in length. The angles of the parallel sides ( base) in the isosceles trapezoid are equal to each other. If the legs or non-parallel sides of the trapezoid are equal in length, then it is called an isosceles trapezoid. There are three types of trapezoids, and those are given below:
