The formula to calculate the area of an isosceles trapezoid is Area = (sum of parallel sides ÷ 2) × height. Resolved Exercises Exercise of the Isosceles Triangle Area Determine the area of a isosceles triangle knowing its two equal sides ( a 3 cm) and the unequal one, whose length is 2 cm ( b 2 cm). This type of triangle where two sides are equal is called an isosceles triangle. What is the Formula for Area of an Isosceles Trapezoid? We can observe that OD and OC are always equal. 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. What is the Difference Between a Trapezoid and an Isosceles Trapezoid? 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°. Find area of the largest possible equilateral triangle inscribed in an isosceles triangle. 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. Finding the height and base of an isosceles triangle whose equal sides are given. In an isosceles trapezoid, the number of sides is four. What are the Properties of an Isosceles Trapezoid? 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.
