What is the formula for Surface Area of a Cone?
S.A. = pi*r^2 + pi*r*l
What are supplementary angles?
Two angles that have a sum of 180 degrees. They make a straight line.
What is the Pythagorean Theorem?
If there is a right triangle, then the sum of the legs squared is equal to the square of the hypotenuse (the longest side).

What is the Converse of the Pythagorean Theorem?
If a^2 + b^2 = c^2, then you have a right triangle.
