![]() ![]() The formula to calculate the area of an isosceles trapezoid is Area = (sum of parallel sides ÷ 2) × height. What is the Formula for Area of an Isosceles Trapezoid? In a trapezoid, each side is of different lengths and the diagonals are not congruent, whereas, in an isosceles trapezoid the non-parallel sides are equal, the base angles are equal, the diagonals are congruent and the opposite angles are supplementary. The solution is: The smaller base is equal to inches. Its important to note that since this is an isosceles trapezoid, both of the non-parallel sides will have the same length. What is the Difference Between a Trapezoid and an Isosceles Trapezoid? To find the perimeter of this trapezoid, first find the length of the larger base. Find the Other Base Angle.Īccording to the property of an isosceles trapezoid, the base angles are equal, therefore if one base angle is 30°, then the other base angle will be equal to 30°. If One Base Angle of Isosceles Trapezoid is 30°. ![]() The two opposite sides (bases) are parallel to each other and the other two sides are equal in lengths but non-parallel to each other. In an isosceles trapezoid, the number of sides is four. As we see the perimeter of the parallelogram is equal the perimeter of the rectangle. What are the Properties of an Isosceles Trapezoid? Since the opposite sides of a palallelogram are equal in length its perimeter is P a + b + a + b or: P 2 a + 2 b. The bases of an isosceles trapezoid are parallel to each other along with the legs being equal in measure. An isosceles trapezoid is a type of quadrilateral where the line of symmetry bisects one pair of the opposite sides. FAQs on Isosceles Trapezoid What is an Isosceles Trapezoid?Īn isosceles trapezoid is a type of trapezoid that has nonparallel sides equal to each other. ![]()
