Across
- 3. The numbers in the set {...,-4, -3, -2, -1, 0, 1, 2, 3, 4,...
- 7. The perimeter of a circle is called its circumference.
- 8. Angle An angle with a measure of less than 90 degrees
- 9. When a line can be drawn through the center of a figure such that the two halves are congruent.
- 10. A collection of numbers, symbols, and/or operation signs that stands for a number.
- 12. The point at which two lines meet
- 13. A number or expression that divides exactly another number (e.g., 1,2,3,4,5,10, and 20 are factors of 20)
- 16. Any part of a whole is called a fraction (e.g., one-half written in fractional form is 1/2
- 17. A line segment from any point on the circle passing through the center to another point on the circle.
- 20. Numbers that correspond to points on a graph in the form (x , y)
Down
- 1. A location in space that has no length or width.
- 2. Figures or objects that are the same shape and the same size
- 4. A mathematical sentence (e.g., 2x = 10) that equates one expression (2x) to another expression (10
- 5. The inside region of a two-dimensional figure measured in square units (e.g., a rectangle with sides of 4 units by 6 units contains 24 square units or has an area 24 square units)
- 6. The shape made by two rays extending from a common end point, the vertex. Measures of angles are described using the degree system.
- 11. The use of rounding and/or other strategies to determine a reasonably accurate approximation, without calculating an exact answer.
- 14. Any symbol that could represent a number
- 15. A straight line that is endless in length
- 18. The common endpoint from which two rays begin (i.e., the vertex of an angle) or the point where two lines intersect; the point on a triangle or pyramid opposite to and farthest from the base.
- 19. A network of evenly spaced, parallel horizontal and vertical lines.
