This lesson plan aims to teach students about angles formed by parallel lines cut by a transversal. It begins with introducing the objectives of defining a transversal and identifying different angles formed. The instructional procedure includes reviewing perpendicular lines, presenting examples and activities, and having students apply their learning by identifying angles in figures. For evaluation, students are asked to identify exterior, interior, alternate interior, and alternate exterior angles. The lesson concludes with an assignment for students to classify different angles in a figure using a transversal.
