Math Cro$$word Puzzle

5. A symbol for a number we don't know yet. It is usually a letter like x or y.
6. On a two-dimensional graph it is where the X axis and Y axis cross, marked (0,0) on the graph here:The starting point
7. four-sided flat shape where every angle is a right angle (90°).
8. Lying next to each other.
9. The ratio of a circle's circumference to its diameter
10. uses letters (like x or y) or other symbols in place of unknown values.
11. The length of the opposite side divided by the length of the adjacent side.
14. the angles opposite each other when two lines cross.
17. Numbers and symbols that show how to work something out.
19. a set of values that show an exact position.
22. The plane containing the "x" axis and "y" axis.
24. Part of the circumference (edge) of a circle or part of any curve.
26. A line that crosses at least two other lines.
28. A 2-dimensional shape made by drawing a curve that is always the same distance from a center.
29. a flat shape with 4 equal straight sides.

1. An angle less than 90°
2. to split into equal parts or groups. It is "fair sharing".
3. When two lines are crossed by another line (which is called the Transversal), the pairs of angles on opposite sides of the transversal but inside the two lines
4. It measures 180° (half a revolution, or two right angles)
12. The side opposite the right angle in a right-angled triangle
13. The length of the opposite side divided by the length of the hypotenuse.
15. The amount of turn between two straight lines that have a common end point (the vertex).

23. an angle of 90°, as in a corner of a square or at the intersection of two perpendicular straight lines.
25. numerator and denominator
27. A reference line drawn on a graph (you can measure from it to find values).
