Exploring Adding and Subtracting Rational Expressions

This video reviews angle relationships, including adjacent, vertical, complementary, and supplementary angles. It provides examples of classifying angle pairs and solving for missing angles using these relationships. The video also covers solving word problems and more complex angle equations using algebra, emphasizing the importance of understanding angle vocabulary.

What defines adjacent angles?

• Angles that sum up to 90 degrees.

• Angles that are opposite each other on intersecting lines.

• Angles that share a common side and vertex.

• Angles that sum up to 180 degrees.

What are vertical angles?

• Angles that are always congruent.

• Angles that share a common side.

• Angles that are adjacent.

• Angles that sum up to 180 degrees.
