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 Shapes Properties
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.
Interior angles add up to 180°
Interior angles add up to 360°
Interior angles add up to 540°
Interior angles add up to 720°
Interior angles add up to 900°
Interior angles add up to 1080°
Interior angles add up to 1260°
Interior angles add up to 1440°
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
