Exploring Angle Vocabulary and Types

This lesson focuses on angles, particularly those formed by parallel lines and a transversal. It covers various types of angles, including adjacent, vertical, alternate, and corresponding angles. The lesson emphasizes understanding the vocabulary and properties of these angles, such as congruence and supplementary angles. Students are encouraged to use mnemonic devices and flashcards to memorize the terms. The lesson also includes exercises to identify angle measures and relationships in diagrams.

What is the term for angles that share a common vertex and side?

• Alternate interior angles

• Corresponding angles

• Diagonal

Which angles are located outside the parallel lines?

• Vertical angles

What are alternate interior angles?

• Angles on the same side of the transversal and inside the parallel lines
