Trapezoid
A quadrilateral with exactly one pair of parallel sides.
A trapezoid is a geometric shape that is defined as a quadrilateral (a four-sided polygon) with two parallel sides, called the bases, and two non-parallel sides called the legs. The legs of a trapezoid are not equal in length, and the two base angles are also not equal. The length of the bases and the length and angle of the legs can vary, creating a variety of different shapes and sizes of trapezoids.
One formula that can be used to find the area of a trapezoid is:
Area = 1/2(base 1 + base 2) × height
In this formula, the height is the perpendicular distance between the two bases. To find the height, one can use the Pythagorean Theorem or the formula:
height = √(leg 1^2 – (1/2(base 2 – base 1))^2)
Another formula that can be used to find the area of a trapezoid is:
Area = (base 1 + base 2)/2 x height
To find the perimeter of a trapezoid, add up the lengths of all of its sides. The perimeter formula for a trapezoid is:
Perimeter = base 1 + base 2 + leg 1 + leg 2
Overall, trapezoids are a useful shape for a variety of applications, including in architecture and engineering, as well as in geometry and mathematics.
