7. A line that passes through two lines in the same plane at two distinct points. The two lines do not need to be parallel. But when the lines are parallel, several special angle relationships are formed.
10. Two rays that share a common endpoint called the vertex of the angle.
12. Two triangles are similar if they have two corresponding angles that are congruent.
13. A polynomial with two terms.
14. Ax^2+Bx+C
15. expressions with exponents that are rational numbers (as opposed to integers).
17. A derived solution to an equation that is invalid in the original equation.
20. A transformation where the orientation of a shape is fliped
23. A triangle congruency statement where two triangles have two angles and one side equal to one and other.
25. A simple and useful statement in geometry that is accepted by the mathematical community as true without proof.
26. The graph of every equation that can be written in the form ax^2+bx+c
28. a(x-h)^2+k
31. Trigonometric ratio of adjacent over hypotonose.
34. The measure of an exterior angle in any triangle is equal to the sum of the two remote interior angles.
35. The origin is a starting point. The coordinates for every other point are based on how far that point is from the origin. At the origin, both x and y are equal to zero, and the x-axis and the y-axis intersect.
38. A function that has a radical and the independent variable is under the square root sign
39. Type of right triangles that can be solved without trig long side to short divide by square root of three
40. the angle formed by a horizontal line and the line of sight of a viewer looking up. Sometimes called the angle of incline.

1. A function whose degree is and where the is not always exactly equal to the function. These types of functions use symbols called inequality symbols that include the symbols we know as less than, greater than, less than, or equal to, and greater than or equal to.
2. A triangle congruency statement where two triangles have three sides equal to one and other.
3. Two angles whose measures add up to 90 degrees
4. when a base graph is multiplied by a certain factor that is greater than 1.
5. The real solutions to a quadratic equation are where it is equal to zero. They are also called zeros or roots. Real zeros correspond to the -intercepts of the graph of a function.
6. A part of a line that has a fixed starting point (endpoint), and then continues toward infinity.
8. The ratios of sides of a right-angled triangle with respect to any of its acute angles
9. formula the opposite of b is plus or minus the square root of b squared - 4ac all over 2a
11. Two non-overlapping angles with a common vertex and one common side.
16. A pair of angles formed by a transversal intersecting two lines. The angles lie outside of the two lines and are on opposite sides of the transversal.
18. Trigonometric ratio of opposite over hypotonose
19. The vertical line that divides the parabola into two congruent halves
21. A Proof that is used to prove that two triangles are similar or similar
22. A triangle congruency statement where two triangles are congruent by having two angles and a side equal to one and other
24. A ray that has its endpoint at the vertex of the angle and divides the angle into two congruent angles.
27. A line that a graph approaches, but does not reach
29. A point on a line segment that divides it into two equal parts.
30. Two angles whose measures add up to exactly 180.
32. the angle formed by a horizontal line and the line of sight of a viewer looking down. Sometimes called the angle of decline.
33. Trigonometric ratio of opposite over adjacent
36. a special type of isosceles right triangle where the two legs are congruent to one another and the non-right angles are both equal to 45 degrees.
37. A polynomial with three terms.
