In this lesson, students will choreograph a figure for a square dance, graph it, and perform it. Media resources and teacher materials are included.

In this video from Cyberchase, Bianca breaks her friend's tabletop when she's practicing dance moves in his living room. She uses measurement and geometry to get a new piece of wood that will fit the table exactly. The accompanying...

This lesson will demonstrate how to use slope, midpoint, and distance formulas to determine, from the coordinates of the vertices if a quadrilateral, if the shape is a square in a coordinate plane. It is 2 of 2 in the series titled...

Discusses air flow around the wing of a plane and its effect upon the lift and drag forces. Focuses on the application of Bernoulli's principle to wing design and the subsequent airfoil shapes.

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

In this lesson make a tangram and experiment with it to make new designs and pictures.

A site dedicated to providing vocabulary for the elements of visual design. Includes a visual notation system for describing both the elements and attributes of art.

These examples demonstrate how to use integration to find the centroid (center of mass) of an object.

Defines polygons and explores characteristics, types of polygons, and how to calculate the area of a polygon.

In Spanish. In these activities you can develop the concept of trajectory. Try to trace the figures without lifting your pencil.

This lesson will present how if two segments from the same point outside a circle are tangent to a circle, then they are congruent. It is 3 of 5 in the series titled "Two Lines Tangent to a Circle."
