Polygons, Angles,<br />
<strong>and</strong> Circles<br />
Real-Life Math<br />
This chapter begins by identifying some of the many places<br />
we see polygons, angles, <strong>and</strong> circles in sports. It explains how<br />
quadrilaterals, spheres, <strong>and</strong> cylinders are used in various sports,<br />
<strong>and</strong> how angles of revolution are used in skateboarding.<br />
Think About It<br />
Choose a sport or game <strong>and</strong> describe how geometry is used in that<br />
sport or game.<br />
What other examples in sports or in a game can you think of that<br />
involve angles? Explain.<br />
Suppose you wanted to build a skateboard ramp. Why would its<br />
shape matter?<br />
Connections to the Past (Grade 5)<br />
Throughout this chapter, you will identify polygons based on the<br />
number of angles <strong>and</strong> sides they have. List all the shapes you can<br />
think of, <strong>and</strong> the number of sides each has.<br />
