From constructing angles to classifying shapes, from solid figures to transformations, these 12 interactive geometry activities will entertain students as they learn.

Types of Lines

Lines are all around you. You can see them in roads, buildings, and even nature. Just like shapes, different kinds of lines have different names. Do you know what they are?

Constructing Angles

Anyone can build an angle. All it takes is a little know-how and the right tool. Got your protractor?

Measuring Angles

Nothing is too hard to measure, not even angles, if you have the right tools. Find out how to capture any angle's measurement anytime!

Classifying Angles

So you know a lot about angles now, but can you classify them? Everything you need to know about classifying angles is right here.

Classifying Triangles

Look around you. Can you find any triangles? Bet you can. You can probably find lots of different kinds of triangles, too, but can you name them?

Classifying Quadrilaterals

Do you know what it takes to be a quadrilateral? To classify shapes, it is important to have every angle covered. We can show you how!

Solid Figures

Movies are great in 3-D, why not geometry? That is exactly what solid figures are all about.

Similar Figures

Look carefully! How can you tell if two figures are exactly the same or just similar? We have the strategies that work.

Lines of Symmetry

Lines of symmetry divide a figure into halves that look like mirror images.

Transformations

It is time to get moving. In math, when you move a figure without changing its shape or size, it is called a transformation. Come see how it works!

Congruent Figures

What do you call two figures that are the same size and shape? No, not identical twins. They are called congruent!

Edges, Faces, Vertices

Can you count the edges, faces, and vertices on your desk? After you check out this section, doing that will be no problem!
