chapters 8 &9 outline
Section 8.3: In this section, you will learn to identify angles by their characteristics and use correct vocabulary to describe and name them. You will also construct triangles and quadrilaterals with given side lengths and/or angles and predict if they will be unique shapes.
Section 9.1: In this section, you will learn about the relationship between the diameter and the circumference of a circle. You will also learn how to calculate the area of a circle from its radius or diameter.
Section 9.2: You will compare how surface area and volume are related by building three‑dimensional rectangular prisms. Then you will visualize the shapes made when you slice prisms and use nets to see the surfaces of a prism.
