Across
- 5. of or pertaining to two numbers related by a congruence.
- 7. the side of a right-angled triangle that is opposite the right angle

- 11. can bisect lines, angles, and more.
- 12. bring the different elements of (a complex activity or organization) into a relationship that will ensure efficiency or harmony.
- 18. straight line which links two points without extending beyond them
- 20. A pyramid is a polyhedron with one face (known as the "base") a polygon and all the other faces triangles meeting at a common polygon vertex
- 22. Passing through or lying on the same straight line.
- 23. any of a series of steps or stages, as in a process or course of action
- 24. neither parallel nor at right angles to a specified or implied line; askew; crooked
- 26. in the period separating
- 27. a general proposition not self-evident but proved by a chain of reasoning; a truth established by means of accepted truths.
- 29. the outside limit of an object, area, or surface; a place or part farthest away from the center of something.
- 30. Something that indicates a border or limit.
- 33. a solid generated by rotating a right triangle about one of its legs —called also right circular cone
- 34. A polygon that has one or more interior angles greater than 180°
- 36. A line which starts at a point with given coordinates, and goes off in a particular direction to infinity, possibly through a second point.
- 38. a line segment extending from the center of a circle or sphere to the circumference or bounding surface
- 39. to assume as a postulate.
- 41. the act or result of construing, interpreting, or explaining
- 42. the length of a straight line through the center of an object
- 44. A plane shape (two-dimensional) with straight sides.
- 45. Mathematics The point of a line segment or curvilinear arc that divides it into two parts of the same length.
- 46. completing or enhancing something.

- 3. An angle whose measure is greater than 90° and less than 180°
- 4. without fixed limits; indefinite in form, extent, or application
- 5. a polygon such that no side extended cuts any other side or vertex; it can be cut by a straight line in at most two points
- 6. an angle of 90°, as in a corner of a square or at the intersection of two perpendicular straight lines.
