  1. 5. Corresponding in size or amount to something else
  2. 8. Two distinct coplanar lines that do not intersect
  3. 10. A polyhedron with eight faces
  4. 12. The distance around the outside of a plane figure. For a polygon, the perimeter is the sum of the lengths of the sides.
  5. 13. An equation, graph, or data that can be modeled by a degree 2 polynomial
  6. 18. The part left over after long division
  7. 19. A set of ordered pairs
  8. 21. An assertion that can be proved true using the rules of logic. A theorem is proven from axioms, postulates, or other theorems already known to be true
  9. 23. Another word for average. Mean almost always refers to arithmetic mean. In certain contexts, however, it could refer to the geometric mean, harmonic mean, or root mean square.

  10. 15. The mathematics of working with variables
  11. 16. The study of geometric figures in two dimensions (plane geometry) and three dimensions (solid geometry). It includes the study of points, lines, triangles, quadrilaterals, other polygons, circles, sp
  12. 17. A line segment between two points on the circle or sphere which passes through the center
