# Test Your Knowledge Of Geometric Shapes With This Quiz!

Image: Original

A shape is described as “the outward form of an object defined by its outline.” Geometry is defined as” the size, relative position, and properties of an object when parameters like scale, orientation and reflection are removed from the equation.” Therefore, moving an object around, enlarging, and rotating it, will result in the same shape.

Throughout kindergarten and high school, we have been taught about these shapes, from the basic yet difficult to draw perfect circle, to more complex structures like dodecagons and icosahedrons. They are classified into different groups based on the number of edges that they have, and can also be labeled as regular and irregular based on whether they follow certain parameters. These geometric shapes can be seen mostly in two- and three-dimensional forms, each of which consist of a set of points and lines which connect in a closed chain.

If you were given images of these different shapes, will you be able to correctly match each one to its name? Will you be one of those people who gets tripped up on the difference between ellipse and ellipsoid or trapezium and trapezoid? Well, many people do. Take this quiz to see if you will be part of the 3% who know all of their shapes. Image: Original
