Shape Clipart

The Math Salamanders have a large bank of free printable shape clipart.

Each of the printable shape sheets is available either in color or black and white.

Using this shape clipart will help your child understand to recognize shapes and learn about the different properties that shapes have.

On the sheets with multiple shapes, we have shown the shapes in different sizes and orientations so that your child will recognize variations of the same shape, and start noticing the properties the same shapes all have.

The sheets can be used as part of a Math display, as flashcards, or as printable coloring sheets.

Regular Polygons Information

All regular 2d shapes, or regular polygons, have special properties listed below.

Regular Shapes Properties

  • All regular polygons have all their sides equal length.
  • All regular polygons have all their angles equal.
  • All regular polygons have the same number of lines of symmetry as their sides.

Regular and Irregular Polygons

Here is a list of regular polygons from 3 to 10 sides.

For each polygon, a regular and an irregular example have been shown.

Any regular polygon will be mathematically similar to the example shown (having the same angles).

There are an infinite number of examples of different irregular polygons that could be shown, and only one example is given.

Equilateral Triangle

The formulae for the interior angles of a polygon are as follows:

Total of interior angles = 180 x (number of sides - 2)

Angle = total of interior angles / number of sides
