2. A segment joining two nonconsecutive vertices of a convex polygon
5. The lines that contain the altitudes of a triangle that are concurrent
7. is a segment passing through the center with endpoints on the sphere.
8. is the quotient of two quantities
10. is a quadrilateral with both pairs of opposite sides parallel
11. interior angles are interior angles that lie on the same side of the transversal
12. is a segment connecting the midpoints of two sides of the triangle.
14. is a parallelogram with four congruent sides and four congruent right angles
15. is a parallelogram with four congruent sides.
16. no line containing a side contains a point within the interior of the polygon
17. compares three (or more) numbers
18. angles lie on the same side of the transversal and in corresponding positions
20. have the exact same shape and size.

1. is a line that intersects two or more co-planar lines at different points.
3. are statements that we accept as true and do not try to prove.
4. is the set of all points equidistant from a given point
6. is a parallelogram with four congruent angles
9. is a segment that has one endpoint at the center and the other endpoint on the circle
13. an equation of a non-vertical line is y = mx + b
19. are statements that we prove using logic, the foundation above, and other previously proved theorems.
