A. If the sides of the trapezoid are equal, the trapezoid is called isosceles. However, in this lesson we focused on an isosceles trapezoid, which is a trapezoid whose non-parallel sides (the legs) are equal in length. The isosceles trapezoid in its bigger base has equal angles, and in its smaller base has also equal angles. Knowing that the smaller base is 4 /3 of the oblique side and that the larger base is 19 /10 of the smaller base, calculates the area of the trapezoid. As such, there could be no such thing as an isosceles trapezoid because if no sides are parallel, then no two sides can be the same length. succeed. Because this is an isosceles trapezoid, the legs are the same length, so you can use 2c in the formula since both the legs are of equal length. The area formula for trapezoids is given by-Area = 1/2 (a+b) h. Perimeter of Trapezoid: The perimeter of a trapezoid is the sum of all its sides.
