Trapezoid - Wikipedia
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, while an obtuse trapezoid has one acute and one obtuse angle on each base.. An isosceles trapezoid is a trapezoid where the base angles have the same ...

Trapezoid bone - Wikipedia
The trapezoid bone (lesser multangular bone) is a carpal bone in tetrapods, including humans.It is the smallest bone in the distal row of carpal bones that give structure to the palm of the hand. It may be known by its wedge-shaped form, the broad end of the wedge constituting the dorsal, the narrow end the palmar surface; and by its having four articular facets touching each other, and ...

Area of a Trapezoid - Math Goodies
A trapezoid is a 4-sided figure with one pair of parallel sides. For example, in the diagram to the right, the bases are parallel. To find the area of a trapezoid, take the sum of its bases, multiply the sum by the height of the trapezoid, and then divide the result by 2, The formula looks like this: or

3 Ways to Find the Perimeter of a Trapezoid - wikiHow
A trapezoid is defined as a quadrilateral with two parallel sides. As with any polygon, to find the perimeter of a trapezoid you need to add all four of its sides together. However, often you will be missing side lengths but have other information, such as the height of the trapezoid, or the angle measurements.
