# Lesson 11

Slicing Solids

Let's see what shapes you get when you slice a three-dimensional object.

### Problem 1

A cube is cut into two pieces by a single slice that passes through points $$A$$, $$B$$, and $$C$$. What shape is the cross section?

### Problem 2

Describe how to slice the three-dimensional figure to result in each cross section.

Three-dimensional figure:

Cross sections:

### Problem 3

Here are two three-dimensional figures.

Describe a way to slice one of the figures so that the cross section is a rectangle.

### Problem 4

Each row contains the degree measures of two supplementary angles. Complete the table.

measure of an angle measure of its supplement
$$80^\circ$$
$$25^\circ$$
$$119^\circ$$
$$x$$
