|
| Free Geometry Topics Available |
| Foundational Geometry Topics |
| The Three Undefined Terms in Geometry - Learn the about the building blocks of all geometry. Without these, everything else will be much more difficult! |
| Three Basic Geometry Vocabulary Terms - the Segment, the ray, and the angle. Learn these very important starting blocks for geometry, but make sure you know the undefined terms first. |
| The Math Pie Symbol - Pi - Curious how pie is a part of math? Take a look at our page on the famous Greek letter pi. |
| |
| Beginning Topics |
| The Pythagorean Theorem - Perhaps the most famous of all the geometry topics. Do not miss GradeA's unique explanation. |
| The Segment Addition Postulate - Learn the Segment Addition Postulate by breaking sticks. This activity really helps give the postulate meaning. |
| Learn How To Measure Angles - An interesting lesson that uses the hands of a clock to demonstrate the different sizes of angles. |
| Learn about Geometry and Triangles - Triangles are categorized by angles and by side lengths. Definitions for acute, right, obtuse, scalene, isosceles, equilateral and equiangular are all given! |
| |
| Formulas |
| Geometry Formulas - A series of important formulas that you will need to know for success in geometry. Topics include, area, coordinate geometry, and right triangles. |
| Circle Formulas- View the Video New! |
| |
| Additional Free Geometry Help Topics |
| Transformation Geometry - Learn about translation, reflections and rotations. |
| More Valuable Geometry Resources from GradeA |
| Because we encourage visually learning so much in geometry, GradeA highly recommends the The Geometer's Sketchpad: A highly affordable program that is a must have for all geometry learners. |
|
 |
To see how effective the Geometer's Sketchpad can be, take a look at our Geometer's Sketchpad Tutorial - an interactive video that teaches the three undefined terms of geometry, as well as the basic functions of the program.
