Parts of a circle
What you'll learn
- Identify and state the theorems relating angles formed by parallel lines and a transversal (corresponding angles, alternate interior angles, alternate exterior angles, same-side interior angles) with 100% accuracy on a matching quiz.
- Apply the theorems relating angles formed by parallel lines and a transversal to solve for unknown angle measures in diagrams, achieving at least 80% accuracy on a worksheet containing 10 problems.
- Explain the logical reasoning behind why the theorems relating angles formed by parallel lines and a transversal are true, using clear and concise language in a paragraph of at least 5 sentences, as assessed by a rubric focusing on accuracy and clarity.
- Construct a two-column geometric proof to demonstrate that if two lines are cut by a transversal such that corresponding angles are congruent, then the lines are parallel, with all statements and reasons justified correctly, as evaluated by a teacher-provided answer key.
