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
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 Angle: 60° Interior angles add up to 180° 
Irregular Triangle 
Square Angle: 90° Interior angles add up to 360° 
Irregular Quadrilateral 
Pentagon Angle: 108° Interior angles add up to 540° 
Irregular Pentagon

Hexagon Angle: 120° Interior angles add up to 720° 
Irregular Hexagon 
Heptagon Angle: 128.6° Interior angles add up to 900° 
Irregular Heptagon 
Octagon Angle: 135° Interior angles add up to 1080° 
Irregular Octagon 
Nonagon Angle: 140° Interior angles add up to 1260° 
Irregular Nonagon 
Decagon Angle: 144° Interior angles add up to 1440° 
Irregular Decagon 
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
