Pi = 3.14159: Use this for finding the circumference of a circle
Area of a Circle: Pi Times Radius Squared = Area, or (Pi x r^2 = A)
Circumference of a Circle: Pi Times Diameter = Circumference, or (Pi x d = C), or you can use:
2 x Pi Times The Radius, or
(2 x Pi x r = C)
Formula for - Area of a Triangle: 1/2 (Base x Height) = Area, or 1/2 (BH)=A
Formula for - Area of a Rectangle: Length x Width = Area, or (L x W = A)
Formula for - Area of a Square: Square the number of one side. (S^2 = A)
Formula for - Perimeter of a Rectangle: 2 x Length + 2 x Width = Perimeter, or (2L + 2W = P)
Angle Bisector: A line or ray that divides an angle in half.
Collinear line: Three or more points lying on the same line.
