Today's lesson focuses on reviewing assignments and exercises from Chapter 5 in Geometry. Students will greet each other and review key points from Assignment #44, covering lessons from pages 200-205. The exercises include Set I (6-23), Set II (32, 44-48), and a bonus problem from Set III. Additionally, there will be a review of angles in a triangle involving ∠CDB, ∠CBD, ∠ADB, and ∠A. A weekly puzzle involves dividing a polygon into two congruent shapes. Homework assignments (Assignment #45) are also introduced, with a test scheduled for Thursday.
