1. A term used to describe a shape whose sides are all of equal length.
4. Two angles that together equal 90°.
5. The ordered pair that gives a precise location or position on a coordinate plane.
6. An angle whose measure is between 0° and 90° or with less than 90° (or pi/2) radians
9. The average is the same as the mean. Add up a series of numbers and divide the sum by the total number of values to find the average.
12. The branch of mathematics that substitutes letters for numbers to solve for unknown values.
15. A number being divided into equal parts (inside the bracket in long division).
17. Point: The "point" at which a line or curve ends.
19. A value that does not change.
22. A procedure or set of steps used to solve a mathematical computation.
23. A number that can be divided or is divisible by 2.
25. Two rays sharing the same endpoint (called the angle vertex).
27. The line dividing an angle into two equal angles.
28. The difference is the answer to a subtraction problem, in which one number is taken away from another.
29. Factors A factor shared by two or more numbers, common factors are numbers that divide exactly into two different numbers.
30. A line segment that connects two vertices in a polygon.

2. A characteristic or feature of an object—such as size, shape, color, etc.—that allows it to be grouped.
3. A metric unit of measurement for length, abbreviated as cm. 2.5 cm is approximately equal to an inch.
7. Objects and figures that have the same size and shape. Congruent shapes can be turned into one another with a flip, rotation, or turn.
8. A line is where two faces meet in a three-dimensional structure.
9. A number involved in an addition problem; numbers being added are called addends.
10. The bottom number of a fraction. The denominator is the total number of equal parts into which the numerator is being divided.
11. The bottom of a shape or three-dimensional object, what an object rests on.
13. A set of numbers or objects that follow a specific pattern.
14. The complete distance around a circle or a square.
16. Digits are the numerals 0-9 found in all numbers. 176 is a 3-digit number featuring the digits 1, 7, and 6.
18. A line that passes through the center of a circle and divides it in half.
20. The unit of an angle's measure represented with the symbol °.
21. two-dimensional space taken up by an object or shape, given in square units.
23. A statement that shows the equality of two expressions by joining them with an equals sign.
24. Always a positive number, absolute value refers to the distance of a number from 0.
26. A number that divides another number into equal parts (outside of the bracket in long division).
