WebA quadrilateral is a 4-sided two-dimensional shape. There are 6 types of quadrilaterals: parallelograms, trapezoids, rectangles, rhombuses, squares, and kites. ️ Parallelograms are quadrilaterals with two sets of parallel sides. A trapezoid is a quadrilateral with exactly one pair of parallel sides. There is no rectangle that is also a trapezoid. In geometry, a trapezoid in American and Canadian English, or trapezium (/trəˈpiːziəm/) in British and other forms of English, is a quadrilateral that has at least one pair of parallel sides. A trapezoid is necessarily a convex quadrilateral in Euclidean geometry. The parallel sides are called the bases of the … See more Ancient Greek mathematician Euclid defined five types of quadrilateral, of which four had two sets of parallel sides (known in English as square, rectangle, rhombus and rhomboid) and the last did not have two sets of … See more A right trapezoid (also called right-angled trapezoid) has two adjacent right angles. Right trapezoids are used in the trapezoidal rule for estimating areas under a curve. An acute trapezoid has two adjacent acute angles on its longer base edge. An obtuse trapezoid … See more Given a convex quadrilateral, the following properties are equivalent, and each implies that the quadrilateral is a trapezoid: • It has two adjacent angles that are supplementary, that is, they add up to 180 degrees. • The angle between a side and a diagonal is … See more There is some disagreement whether parallelograms, which have two pairs of parallel sides, should be regarded as trapezoids. Some define a trapezoid as a quadrilateral having … See more Four lengths a, c, b, d can constitute the consecutive sides of a non-parallelogram trapezoid with a and b parallel only when See more The midsegment (also called the median or midline) of a trapezoid is the segment that joins the midpoints of the legs. It is parallel to the bases. … See more The area K of a trapezoid is given by $${\displaystyle K={\frac {a+b}{2}}\cdot h=mh}$$ where a and b are the lengths of the parallel sides, h is … See more
