Investigation 2: Using a Compass and Straightedge, Part 1
Properties of a Circle is a key Grade 7 math skill in Saxon Math, Course 2. The distance around a circle is its circumference. The distance from the center to a point on the circle is the radius. The distance across the circle through its center is the dia Think of the basic parts of a circle like ordering a pizza.
Key Concepts
New Concept The distance around a circle is its circumference . The distance from the center to a point on the circle is the radius . The distance across the circle through its center is the diameter , which equals two radii. $$ d = 2r $$ What’s next Next, you’ll use these concepts in hands on activities. We'll practice drawing concentric circles, inscribing polygons, and dividing a circle into equal sectors using a compass.
