This site provides definitions of different types of polygons and figures.

This website has basic definitions for most polygons, regular and irregular.

This lesson focuses on polygons; a polygon is a closed, flat shape that has only straight sides. Polygons can have any number of sides and angles, but the sides cannot be curved.

Explore and measure a variety of quadrilaterals.

This activity is designed as an introduction to using the Carbri Jr. application on the TI-83+/84+ calculators. Students are guided through the menu system and are shown how to draw triangles, quadrilaterals and and a pentagon. Perimeter...

Students understand that a tessellation is covering of a plane with a pattern of figures so there are no overlaps or gaps. They draw quadrilaterals and triangles and explore monohedral, dihedral, and trihedral tessellating patterns.

Challenge problems involving the coordinates of the vertices of the quadrilaterals Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

This lesson focuses on quadrilaterals which can fall into multiple categories based on the number of sides and the angles.

Learn about quadrilaterals, polygons, and transformation by taking a look at examples and a video lesson.
