To calculate the area of a trapezoid, identify the measurements of the two parallel sides and the distance between them. Put those numbers into the formula for calculating the area of a trapezium, and solve the equation. More » Math Geometry Trigonometry

The area of any trapezoid with base side lengths "b1" and "b2" and height "h" is given by the formula A = h(b1 + b2)/2. The base sides are the trapezoid's two parallel sides. The trapezoid's height is the length of a per... More »

Calculate the area of a trapezoid by identifying the length of the two parallel bases and the height of the polygon. Then, use the formula A = a + b/2 (h), where "a" and "b" are the two parallel base lengths and "h" refe... More »

A trapezoid is a quadrilateral with two parallel sides and, usually, two nonparallel sides. A quadrilateral is a geometric shape that has four sides. Some specialized types of trapezoid are the parallelogram and the isos... More »

A trapezoid is a four-sided shape that has only two parallel sides. Most quadrilaterals have two pairs of parallel sides for four sides total, such as squares, rectangles, rhombuses and parallelograms. More »

An online right triangle calculator is a program that calculates the unknown side lengths or angle measurements. It uses the known side length and angle measurements for its calculations. More » Math Geometry Trigonometry

Pythagoras often receives credit for the discovery of a method for calculating the measurements of triangles, which is known as the Pythagorean theorem. However, there is some debate as to his actual contribution the the... More »
