Basic Principles of Geometry

In this last lesson on measurement of segments, review two challenging geometry problems involving congruent segments and algebra.

In this lesson, review how to name and denote angles by their vertex or sides, and find out how to measure angles with a protractor and denote them properly.

Now that you’ve reviewed angle terminology and practiced measuring them, find out how to classify angles according to size in this lesson from Math Fortress.

Review the parts of a degree, learn how to denote measurements clearly, and understand the definition of congruent angles and how to denote congruence.

In this lesson, review examples and exercises on measuring angles. This is a chance to follow keep the geometric concepts you’ve just learned active.
