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 »

The first recorded use of inclined planes in construction happened around 2600 B.C. when ramps were used in the construction of the Great Pyramids. It is likely, however, that both natural and artificial inclined planes ... More »

The ramp, wedge and screw are simple machines belonging to the inclined plane family. Inclined planes makes it easier to move an object. Lifting an object vertically requires a great amount of force. Using a ramp require... More » Science Physics Motion & Mechanics

Some tips for geometry proof practice are to break the problem down into smaller pieces, to label all necessary points, lines and planes and to write down the reasoning for each step. Another tip is to understand the pro... More » Math Geometry

Two distinct planes intersect at a line, which forms two angles between the planes. Planes that lie parallel to each have no intersection. More »

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 »

Turtle shells, honeycombs, raspberries, quilts, fish scales and the art of M.C. Escher are just a few examples of real-life tessellations. Tessellations are patterns that repeat over and over without overlapping or leavi... More »
