Rules Postulates Theorems
In most areas of math, special rules are used to help solve problems. This section lists many of these rules such as definitions, postulates, theorems, corollaries and formulas that are used in geometry. Certain ones are especially important to know when doing a geometry proof. To help with finding a particular geometry rule, the rules are placed in their most appropriate category and are listed alphabetically.
The rules are described in their area of geometry that follows. The basic category lists geometry rules for lines, planes, angles, other simple geometric figures and their relationships.
The rules of geometry are also listed in alphabetical order with links to their description.
