C. LEARNING OBJECTIVES By using the Scientific approach, the method of discussion, question and answer and by using the Cooperative Type STAD model, students are expected to grow curiosity, cooperation, and discipline. And can prove the Phytagorean theorem equilateral triangles and know the side-to-side comparisons of right-angle triangles with special angles. D. LEARNING MATERIALS 1. Proof of the Pythagorean theorem with Equilateral Triangles 2. Side-to-Side Comparison of Right-Angle Triangles with Special Angles E. MODEL APPROACH OR LEARNING METHOD Approach
