Geometry: Trapezoids are an important concept in geometry and are often used as an example of a polygon with parallel sides. The importance of trapezoids lies in their various practical applications in different fields, such as: Working with trapezoids in geometry and other mathematical applications. Varying properties and characteristics, and understanding them is important for In summary, the different types of trapezoids have Thought of as a special case of a trapezoid in which the two parallel sides are In which both pairs of opposite sides are parallel. Parallelogram: A parallelogram is a type of trapezoid Quadrilateral with one pair of parallel sides. Trapezium: In the United States, however, the term trapezium is notĬommonly used, and the term trapezoid is used to refer specifically to a Sides, and h is the height of the trapezoid. 2] * h, where AB and CD are the lengths of the parallel The formula for the area of a scalene trapezoid is Isosceles if and only if the base angles are congruent. trapezoid and its theorems Theorem 1: A trapezoid is When non-parallel sides in trapezoid areĮqual then it is known as isosceles trapezoid. Unless you are given (or can prove) that information. Never assume that a trapezoid is isosceles Is one half the sum of the lengths of the bases. Median (or mid-segment) of a trapezoid is parallel to each base and its length Trapezoid is isosceles if and only if the diagonals are congruent.Ī trapezoid is isosceles, the opposite angles are supplementary. Let's go through each of the properties of a trapezoid in detail, withĪ trapezoid is isosceles if and only if the baseĪ trapezoid is an isosceles trapezoid if and only if the non-parallel
