# 2-6 Skills Practice Proving Angle Relationships

Proving angle relationships is an important part of geometry that helps people understand the properties of angles. It is used to prove trigonometric identities and other geometrical results. The 2-6 skills practice is a series of exercises designed to help students gain a better understanding of angle relationships and how to prove them.

In the 2-6 skills practice, students are asked to draw an angle and then prove the relationships between it and other angles in the problem. This involves using theorems and definitions to state the relationships between angles and then proving that they are true. Theorems like the Angle Bisector Theorem, Triangle Inequality Theorem, and Alternate Interior Angle Theorem are particularly useful in this type of problem.

In addition to theorems, students can also use postulates and definitions to prove angle relationships. Postulates like the SAS Postulate and Triangle Sum Theorem are commonly used to prove angle relationships. Definitions like the definition of complementary angles and supplementary angles can also be used in the 2-6 skills practice.

To complete the 2-6 skills practice, students must also be able to identify and use the properties of special angles like right angles, acute angles, and obtuse angles. Knowing the properties of these angles can help students identify the relationships between them and other angles in the problem. Additionally, students should be familiar with the properties of circles and arcs so they can find the measures of angles.

Proving angle relationships is an important part of geometry that can help students better understand the properties of angles and how to prove them. The 2-6 skills practice is a great way for students to practice proving angle relationships and to gain a better understanding of theorems, postulates, and definitions related to angle relationships.
