Across
- 7. the angle formed when two chords intersect on the circle
- 8. two angles that add up to equal 90 degrees
- 10. a straight line that touches the outside of the circle and is horizontal to the arc on the circle
- 11. used to find missing side lengths in right triangles
- 13. an arc that is smaller than 180 degrees
- 14. points, shapes, or lines that exist in the same geometric plane
- 15. an arc that is 180 degrees exactly
- 16. two angles that add up to equal 180 degrees
Down
- 1. angles that are directly across from each other when two lines intersect
- 2. a line segment whose endpoints both lie on a circle
- 3. a straight line that cuts an arc into two or more parts
- 4. two dimensional shape with no corners, sides, or edges
- 5. two angles with common side and a common vertex, but do not overlap
- 6. circles with a common center but of different sizes
- 9. an arc that is bigger than 180 degrees
- 12. the leg diagonally across from the 90 degree angle in a right triangle
