- 8. A line segment, line, or plane that divides a geometric figure into two congruent halves.

- 21. When two lines intersect, four angles are formed.
- 23. The geometric figure formed at the intersection of two distinct lines.
- 25. Two angles in a plane which share a common vertex and a common side but do not overlap.
- 27. A three dimensional solid consisting of all points equidistant from a given point.
- 29. The geometric figure formed by two points.
- 30. if you can connect two vertices (the corners) of a polygon and have all or part of the line go OUTSIDE the polygon
- 31. formed when two lines intersect.
- 34. If the denominator of a fraction is 0, then the fraction is undefined.

Down
- 1. A polyhedron with a polygonal base and lateral faces that taper to an apex.
- 2. The distance from the center of a circle to any point on its circumference.
- 3. A set of logical arguments used to deduce or prove a mathematical theorem from a set of axioms.
- 4. a true statement, which does not require to be proved.
