make up the set of real numbers ||
 * Term || Lesson || Definition ||
 * Abscissa || 3-7 || The first number in the ordered pair is the x-coordinate or abscissa ||
 * Converse || 3-5 || If you reverse the parts of the Pythagorean Theorem, you have formed its converse. ||
 * Coordinate Plane || 3-7 || Recall that you can locate a point by using a coordinate system similar to the grid used by the mountain biker. It is called a coordinate plane. ||
 * Hypotenuse || 3-5 || The hypotenuse is the side opposite the right angle. It is the longest side of the triangle. ||
 * <span style="font-family: Georgia,serif;">Irrational Number || <span style="font-family: Georgia,serif;">3-4 || <span style="font-family: Georgia,serif;">Numbers that are not rational are called irrational numbers ||
 * <span style="font-family: Georgia,serif;">Legs || <span style="font-family: Georgia,serif;">3-5 || <span style="font-family: Georgia,serif;">the two shortest lines on a right triangle ||
 * <span style="font-family: Georgia,serif;">Ordered Pair || <span style="font-family: Georgia,serif;">3-7 || <span style="font-family: Georgia,serif;">Any point on the coordinate plane can be graphed by using an ordered pair of numbers. ||
 * <span style="font-family: Georgia,serif;">Ordinate || <span style="font-family: Georgia,serif;">3-7 || <span style="font-family: Georgia,serif;">Any point on the coordinate plane can be graphed by using an ordered pair of numbers ||
 * <span style="font-family: Georgia,serif;">Origin || <span style="font-family: Georgia,serif;">3-7 || <span style="font-family: Georgia,serif;">The origin is the point of intersection of the two number lines. ||
 * <span style="font-family: Georgia,serif;">Perfect Square || <span style="font-family: Georgia,serif;">3-1 || <span style="font-family: Georgia,serif;">Numbers such as 1, 4, 9, 16, and 25 are called perfect squares because they are squares of integers ||
 * <span style="font-family: Georgia,serif;">Pythagorean Theorem || <span style="font-family: Georgia,serif;">3-5 || <span style="font-family: Georgia,serif;">The Pythagorean Theorem describes the relationship between the lengths of the legs and the hypotenuse for any right triangle ||
 * <span style="font-family: Georgia,serif;">Quadrants || <span style="font-family: Georgia,serif;">3-7 || <span style="font-family: Georgia,serif;">Quadrants are four sections of the coordinate plane. ||
 * <span style="font-family: Georgia,serif;">Radical Sign || <span style="font-family: Georgia,serif;">3-1 || <span style="font-family: Georgia,serif;">The symbol √􏰀, called a radical sign ||
 * <span style="font-family: Georgia,serif;">Real Number || <span style="font-family: Georgia,serif;">3-4 || <span style="font-family: Georgia,serif;">The set of rational numbers and the set of irrational numbers together
 * <span style="font-family: Georgia,serif;">Square Root || <span style="font-family: Georgia,serif;">3-1 || <span style="font-family: Georgia,serif;"> A square root of a number is one of its two equal factors. ||
 * <span style="font-family: Georgia,serif;">X-Axis || <span style="font-family: Georgia,serif;">3-7 || <span style="font-family: Georgia,serif;">Goes side to side. ||
 * <span style="font-family: Georgia,serif;">X-Coordinate || <span style="font-family: Georgia,serif;">3-7 || <span style="font-family: Georgia,serif;">The first number in the ordered pair is the x-coordinate or abscissa ||
 * <span style="font-family: Georgia,serif;">Y-Axis || <span style="font-family: Georgia,serif;">3-7 || <span style="font-family: Georgia,serif;">Goes up and down. ||
 * <span style="font-family: Georgia,serif;">Y-Coordinate || <span style="font-family: Georgia,serif;">3-7 || <span style="font-family: Georgia,serif;">The second number is the y-coordinate or ordinate. ||
