A trapezoid is a quadrangle that is not a parallelogram. A trapezoid is a quadrangle because it has four sides and four internal angles, but it is not a parallelogram because it only has one pair of parallel sides rather than two.
Each of the two parallel sides is called a base of the trapezoid, and each of the two non-parallel sides is referred to as a leg. The perimeter of the trapezoid is determined by adding the lengths of all four sides together. The formula for the area of the trapezoid requires multiplying the height by the sum of both bases and dividing by two.Learn More
There are three types of trapezoid. There is the right trapezoid, which has two right angles, isosceles trapezoid, which has two of its non-parallel sides equal in length and the scalene trapezoid, which does not have equal sides or angles.Full Answer >
The area of a trapezoid is found by multiplying the average length of the two parallel bases by the height, or 1/2 (b1 + b2) x h. The height is the length of a line connecting one base to the other at a 90-degree angle.Full Answer >
The midsegment of a trapezoid is a line that connects to the midpoints of the two non-parallel sides of a trapezoid, according to The Geometry Center at the University of Minnestota. The midsegment of a trapezoid runs parallel with the two other parallel sides.Full Answer >
A trapezoid may have right angles, but they are not required. The definition of a trapezoid only specifies that it must be a quadrilateral, or a closed, four-sided shape, and that it must have only one pair of parallel sides.Full Answer >
