To find the volume of a rectangular prism, divide it into fractional cubes, find the volume of one cube, then multiply that area by the number of cubes.

Find the volume of a rectangular prism with fractional dimensions.

Learn how to rearrange the parts of geometric figures to find the area.

This tutorial explains that a reflection point is the mirror point on the opposite axis--like looking at a mirror image of yourself, but flipped.

A polyhedron ("polyhedra" is plural) is nothing more than a 3 dimensional shape with flat surfaces and straight edges. (Think: cube.)

Find the area of odd-looking geometric figures by breaking the figure up into smaller, simple geometric shapes, then calculate and total their areas.

Surface area is the sum of all the areas of all the shapes that cover the object's surface. Let's use the net of polyhedra as an example.

What's interesting about the opposite sides of a parallelogram? That's right....they are parallel! Let's find the area--base x height.

Learn how to find the volume of a rectangular prism through a word problem.

If you were going to make your own kite out of a piece of cloth, then knowing the area of the kite would be helpful, right?

Some quadrilaterals are oddly shaped so break it up into shapes for which the area is more easily determined.

In this example we're given the coordinates of the vertices and asked to construct the resulting polygon a quadrilateral). This is fun!

This geometry primer explains the basics of perimeter and area.

A trapezoid is a cousin of the parallelogram. However, in a trapezoid only two of the opposing sides are parallel. Here's how to find its area.

Learn the definition of quadrilaterals, the difference between concave and convex quadrilaterals, and about trapezoids, parallelograms, and rhombi.
