Basic Principles of Geometry

Build on your geometry knowledge with more challenging exercises on the parts of a degree. Math Fortress explains the complexities of this basic concept.

Get more practice measuring angles. Begin by measuring the degrees between clock hands, then practice determining measurements based on given congruent angles.

Challenge yourself further with exercises in which students determine an angle’s measurement by first solving for X in algebraic expressions.

This lesson from Math Fortress includes basic to intermediate geometry problems in which students measure angles through algebraic expressions and inequalities.

In this final lesson on measurement of angles, follow along as Math Fortress solves two challenging geometry problems that require the use of algebra.
