  Pythagorean Theorem

  a2 + b2 = c2, where a and b are the lengths of the legs of a right triangle, and c is the length of the hypotenuse.

  Area of a Triangle

  Area = bh, where b is the length of the base and h is height.

  Sum of the Interior Angles of a Polygon

  The sum of the interior angles of a polygon is (n – 2)180°, where n is the number of sides in the polygon.

  Area of a Trapezoid

  Area = h, where s1 and s2 are the lengths of the bases of the trapezoid, and h is the height.

  Area of a Parallelogram, Rectangle, and Rhombus

  Area = bh, where b is the length of the base, and h is the height.

  Area of a Square

  Area = s2, where s is the length of a side of the square.

  Circumference of a Circle

  Circumference = 2πr, where r is the radius of the circle.

  Arc Length

  Arc Length = 2πr, where n is the measure of the degree of the arc, and r is the radius of the circle.

  Area of a Circle

  Area = πr2, where r is the radius of the circle.

  Area of a Sector

  Area of Sector = πr2, where n is the measure of the central angle which forms the boundary of the sector, and r is the radius of the circle.
