 * **Term** || **Lesson** || **Definition** ||
 * **Abscissa** ||  || the first number of an ordered pair ||
 * **Converse** ||  || when the parts of a theory are reversed. ||
 * **Coordinate Plane** ||  || where a horizontal and a vertical line intersect at the the zero ||
 * **Hypotenuse** ||  || the side opposite the right angle in a right triangle ||
 * **Irrational Numbers** ||  || go on forever with no pattern can not be expressed as a fraction (pi) ||
 * **Legs** ||  || the short sides of the right triangle ||
 * **Ordered Pair** ||  || the numbers on a graph that look like (3,6) ||
 * **Ordinate** ||  || the second number of an ordered pair (y coordinate) ||
 * **Origin** ||  || 0 on a coordinate plane ||
 * **Perfect Square** ||  || where the number comes out without a decimal ||
 * **Pythagorean Theorem** ||  || the squared hypotenuse is equal to the sum of the legs squared ||
 * **Quadrants** ||  || the four boxes that the lines in a coordinate plane separate ||
 * **Radical Sign** ||  || the sign that shows to square root it ||
 * **Real Number** ||  || irrational and rational numbers together ||
 * **Square Root** ||  || like 144's square root is 12 and 12 squared is 144 ||
 * **X-Axis** ||  || the horizontal line ||
 * **X-Coordinate** ||  || first number in an ordered pair (__//**3**//__,6) ||
 * **Y-Axis** ||  || the vertical line ||
 * **Y-Coordinate** ||  || the second number of an ordered pair (3,__**//6//**__) ||
