ALGEBRA FINAL

1. . A polygon with six sides
3. 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
5. Straight up and down
10. A polyhedron with eight faces
13. The top part of a fraction
14. An equation, graph, or data that can be modeled by a degree 2 polynomial
16. A set of ordered pairs
18. Corresponding in size or amount to something else
21. Like a line. A description of any graph or data that can be modeled by a linear polynomial
22. A geometric figure in three dimensions excluding interior points, if any
24. A line segment between two points on the circle or sphere which passes through the center

2. 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
4. A polygon with seven sides
6. Two distinct coplanar lines that do not intersect
7. The product of a given integer and all smaller positive integers.
8. Half a circle. That is, a 180°
9. The result of dividing two numbers or expressions. For example, the 40 divided by 5 has a quotient of 8
11. A mathematical sentence built from expressions using one or more of the symbols <, >, ≤, or ≥.
12. A curve usually expressed in polar coordinates that resembles a figure eight.
15. The mathematics of working with variables
17. 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.
19. The distance around the outside of a plane figure. For a polygon, the perimeter is the sum of the lengths of the sides.
20. The part left over after long division
23. The matrix formed by taking the transpose of the cofactor matrix of a given original matrix
