This MathWorld tutorial provides detailed overviews of the concepts and theorems associated with geometry. Most of the Math World sites are extensive and some require higher math knowledge to understand, links to terms and topics are...

This webpage discusses projections, providing two diagrams. This is a great source if you are using it as a reference tool to refresh the fundamentals and formula. This site gives links to related topics.

Geometry is the study of how to use math to describe and investigate different points, lines and shapes. The way that a shape is described in geometry is with a formula, which is simply a mathematical way to calculate different...

Here is a project that combines Computer Science and Mathematics. Prove a method for inscribing a circle within a triangle (as shown). You'll also learn how to create an interactive diagram to illustrate your proof, using an applet that...

[Free Registration/Login may be required to access all resource tools.] In this lesson students will study scalar projections: dot products of vectors and unit vectors. Students examine guided notes, review guided practice, watch...

The students will be split into small, cooperative groups and build a city following specific guidelines. The students will learn how a city is constructed with angles, intersections, parallel, intersecting, and transversal streets. They...

This site from The Galileo Project of Rice University contains information about Cardano's life in an outline format. Some topic headings are nationality, education, religion, scientific disciplines, means of support, and many more.

Students will participate in several activities that will build their knowledge of coordinates graphing. Students will use ordered pairs to locate points on a grid. Students will also relate coordinate graphing to the real world through...

Juice boxes are so convenient, just poke the straw in and sip away. It might surprise you how much thought goes into the design and manufacturing of a juice box. Each manufacturer has carefully calculated how big each side should be to...

A good beginner's site for fractals - the language is straightforward and requires only minimal experience to be able to understand the topic. (Note: When clicking on links on archived site, they may pause and appear not to be found...

This site from The Galileo Project of Rice University contains an outlined biography of James Gregory. A lot of information is contained in this site, with the topics including: dates, father, nationality, education, religion, and so on.

This is an interesting geometry project that goes back to the time of Archimedes, the famous Greek mathematician. You can combine this mathematical project with computer science and take this ancient problem into the twenty-first century...

This a straightforward, but interesting, project in geometry. It is a good first proof to try on your own. You should be able to figure it out by yourself, and you'll gain insight into a basic property of circles.

For this series of STEAM activities, students will discover the concepts of geometry through shape exploration and the creation of choreographic sequences. Another activity in this module will allow students to identify shapes by...

If art and math are both passions of yours, this project is meant for you! Spidrons are geometric forms made from alternating sequences of equilateral and isosceles (30 degrees, 30 degrees, 120 degrees) triangles. Spidrons were...

Here is a project that combines Computer Science and Mathematics. Prove a method for circumscribing a circle about a triangle (as shown). You'll also learn how to create an interactive diagram to illustrate your proof, using an applet...

What is it that famous photographers do to make their images so pleasing to the eye? Find out if simple rules of geometry and symmetry can make you a better photographer.

The arbelos is the white-shaded region between the three semicircles in the illustration at right. In this project, you'll prove an interesting method for determining the area of the arbelos.

Here is a project that combines Computer Science and Mathematics. The two circles are tangent to one another at point A. Their diameters are parallel. Prove that points A, D and F are co-linear. You'll also learn how to create an...

Here is a project that combines Computer Science and Mathematics. The semicircle has two tangent lines that meet at point T. You need to prove that a line drawn from A to T bisects CD. You'll also learn how to create an interactive...

A unique geometry project that asks students to complete a transformation using a picture. Project includes instructions, examples, and quiz questions.

Follow along as a teacher demonstrates how to encourage students to be creative when planning and demonstrating a learned skill.

Learners will work in groups to design a card table. Students will communicate with each other through a class blog or class discussion page. Learners will then work in groups to design a card table. After the design phase, students will...

Students learn about trigonometry, geometry and measurements while participating in a hands-on interaction with LEGO MINDSTORMS NXT technology. First they review fundamental geometrical and trigonometric concepts. Then, they estimate the...
