Chapter Overview
This chapter focuses on understanding the concept of area in the context of parallelograms and triangles. It emphasizes the use of base and height, properties of figures on the same base and between the same parallels, and introduces students to logical reasoning behind area relationships and formulas through geometrical proofs.
