# 1.5 Angle Relationships Worksheet Answers

Angles are one of the most fundamental concepts in geometry and trigonometry. Understanding angles and the relationships between them is important for students to master in order to be successful in math. The 1.5 Angle Relationships worksheet is a great way for students to practice and review the basic concepts of angles and their relationships. This worksheet includes questions about angles, angles of elevation and depression, complementary and supplementary angles, and linear pairs.

The worksheet starts off by asking students to identify different types of angles. Students must be able to recognize right, acute, obtuse, and straight angles. Next, the worksheet moves on to angles of elevation and depression. To answer these questions, students must understand the meaning of angles of elevation and depression and be able to calculate them using the given information. After that, the worksheet includes questions about complementary and supplementary angles and linear pairs.

Complementary angles are two angles that add up to 90 degrees, while supplementary angles add up to 180 degrees. To answer these questions, students must be able to identify the angles in the given problem and determine whether they are complementary or supplementary angles. Linear pairs are two angles that are adjacent and form a straight line. To answer these questions, students must be able to identify the angles and determine if they are a linear pair.

The 1.5 Angle Relationships worksheet also includes questions about solving for unknown angles. To answer these questions, students must be able to use the given information to solve for the unknown angle. Finally, the worksheet includes questions about finding the measure of an angle given the length of two sides of the angle. To answer these questions, students must be able to use the Law of Sines or the Law of Cosines to find the angle.
