Midterm Review Part I: Solving Collinear and Coplanar Problems in Geometry

This midterm review covers key concepts in geometry related to collinearity and coplanarity. It includes step-by-step solutions for solving equations involving collinear points and coplanar lines. The review also addresses alternate exterior angles and their properties, same-side angles, and supplementary angles. Students will find equations to solve for variables, using strategies such as the slope formula and point-slope form. Each section includes practice problems to solidify understanding and prepare for the exam.
