Across
- 7. A statement that shows the equality of two expressions by joining them with an equals sign.
- 10. The line dividing an angle into two equal angles.
- 13. The mean is the same as the average. Add up a series of numbers and divide the sum by the total number of values to find the mean.
- 15. The study of lines, angles, shapes, and their properties. Geometry studies physical shapes and the object dimensions.
- 16. The branch of mathematics that substitutes letters for numbers to solve for unknown values
- 17. A line segment that connects two vertices in a polygon.
- 19. The two-dimensional space taken up by an object or shape, given in square units.
- 20. A metric unit of measurement for length, abbreviated as cm. 2.5 cm is approximately equal to an inch
Down
- 1. A line that passes through the center of a circle and divides it in half.
- 2. An equation that contains two variables and can be plotted on a graph as a straight line.
- 3. The bottom of a shape or three-dimensional object, what an object rests on.
- 4. A three-dimensional shape with only one vertex and a circular base.
- 5. A polynomial equation with two terms usually joined by a plus or minus sign.
- 6. 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 three-dimensional shape featuring two circle bases connected by a curved tube.
- 9. A straight line touching a curve from only one point.
- 11. A number that divides into another number exactly. The factors of 10 are 1, 2, 5, and 10 (1 x 10, 2 x 5, 5 x 2, 10 x 1).
- 12. The mode in a list of numbers are the values that occur most frequently.
- 14. The volume of substance that a container will hold
- 18. Two rays sharing the same endpoint (called the angle vertex).
