Regular pentagons have five equal sides and five equal angles. Percent - A ratio or fraction in which the second term on denominator is always 100. Perimeter - The total distance around the outside of a polygon. The total distance around is obtained by adding tegether the units of measure from each side.

Pi is used to represent the ratio of a circumference of a circle to its diameter. Plane - When a set of points joined together form a flat surface, the plan can extend without end in all directions. Polynomial - An algebraic term. The sum of 2 or more monomials. Polynomials include variables and always have one or more terms. Polygon - Line segments joined together to form a closed figure. Rectangles, squares, pentagons are all examples of polygons. Prime Numbers - Prime numbers are integers that are greater than 1 and are only divisible by themselves and 1. Probability - The likelihood of an event happening. Product - The sum obtained when any two or more numbers are multiplied together.
