- segment passing through the center of a circle with both end points on the circle
- irrational number
- a number that cannot be expressed as a rational number in the form of a over b and b b is not equal to zero. As a decimal, it is a nonrepeating, non terminating decimal
- rational number
- a number that can be written in the form of a/b where a and b are integers and b doesnot equal 0. Zero and repeating or terminating decimals make up the set of rational numbers

- line
- a set of points in order extending indefiantley in opposite directions
- perpendicular lines
- lines in a plane that intersect to form right angles
- inverse relationships
- opposite operations: addition and subtraction are inverse relationships,; multiplication and division are inverse realationships
