Module 3-1 Practice

In this practice module, we explore linear pairs and their properties. A linear pair consists of adjacent angles whose noncommon sides are opposite rays, summing up to 180°. We will apply relevant theorems and postulates to find the value of "X" in various cases. Additionally, today's classwork includes exercises focusing on corresponding angles, alternate interior angles, alternate exterior angles, same-side interior angles, vertical angles, and supplementary angles. Students are tasked with completing problems on page 82 while referencing the theorems discussed.
