Real-life examples of trapezoids include certain table tops, bridge supports, handbag sides and architectural elements. Since a trapezoid cannot be three-dimensional, many real-life examples of trapezoids are only partly... More »

Parallel lines exist everywhere in everyday life, including on the sides of a piece of paper and the way that the shelves of a bookcase are positioned. Parallel lines are two or more lines that when drawn out infinitely ... More »

Some real-world examples of a trapezoid include a typical bicycle frame, the wings on an airplane, most tables, most desks and some purses. A trapezoid is a shape that has four sides, is flat and has a pair of parallel o... More »

The factorial of the number 0 is defined as 1 because there is only one possible permutation for a set of zero elements, namely the empty set. The combinatorial interpretation of the factorial function is the total numbe... More »

There are many different types of quadrilaterals: squares, rectangles, rhombuses, trapezoids, parallelograms and kites. A quadrilateral defined as a closed shape (polygon) that consists of exactly four straight lines. More »

How much weight a beam bridge can hold depends on the materials it is made of and the distance between its supports. Typically, a singular beam bridge is a maximum of 250 feet long, but several beam bridges can be combin... More »

Some examples of inclined planes include wheelchair ramps, airplane evaluation slides and various loading ramps used on trucks. An inclined plane refers to any structure that is oriented on an angle, which resembles a tr... More »
