Across
- 3. The measure of this is always half of that of the central angle that defines the same arc (two words)
- 7. A section of a circle’s circumference
- 9. Every triangle has one of these. If a circle is centered here, it can be the largest possible circle that can fit within the triangle
- 10. pi * diameter solves for this
- 11. A line segment between two points on a circle's circumference
- 12. A chord that passes through the center of the circle
- 14. An angle between a point on the circle, the center, and another point on the circle (two words)
Down
- 1. 180 degrees is equal to pi of these
- 2. A section of a circle’s area, defined by a central angle
- 4. This is equal in length to a radian of the circle
- 5. There are 360 of these in a circle
- 6. A line with one intersection with a circle, and the line is perpendicular to a drawn radius on a circle
- 8. Every triangle has one of these. If a circle is centered here, it can go through all three vertices of the triangle
- 11. A shape where all points are equidistant from one point, the center
- 13. pi * radius ^ 2 solves for this
