SAT Math Lesson Plan 23: Lines and Angles

In SAT Math Lesson 23, students will learn how to identify and analyze angle relationships when parallel lines are cut by a transversal. This lesson covers:

SAT

 

  • Recognizing corresponding, alternate interior, alternate exterior, and same-side angles,
  • Using congruence and supplementary relationships to solve for unknown angles,
  • Applying geometric reasoning to SAT-style diagrams, and
  • Writing and solving equations involving angle measures.

The lesson provides clear, step-by-step instruction with worked examples that show how to solve problems involving angle relationships. Students will gain confidence interpreting diagrams and applying angle theorems, a common focus on the SAT Math section. By the end of the lesson, students will be better equipped to solve geometry problems involving transversals and angle relationships.
