Question

1. practice: making mental images

describe two ways to construct a cone.

1. grow the cone from its ______.

stack ______ discs that get smaller until it reaches a point at the vertex.

1. enclose the cone with its base and lateral face.

base: 1 ______
lateral face: 1 section of a ______ wrapped around the base

1. practice: activating prior knowledge and using visual cues

name each solid. remember to tell if the solid is right or oblique.
then label each base and vertex.

1. practice: activating prior knowledge and organizing information

complete the chart. write 1, 2, or 3 in each blank.

Explanation:

Step1: First way to construct a cone

Stack circular discs that get smaller until it reaches a point at the vertex. We start from the base - which is a circle, and grow the cone from its base.

Step2: Second way to construct a cone

The base of a cone is 1 circle. The lateral face is 1 section of a circle (a sector) wrapped around the base.

Answer:

1. base; circular
2. circle; sector
