GEOMETRIC EQUATIONS
SQUARE
= ANY
SIDE SQUARED.
RECTANGLE
= ONE SIDE x
THE BASE.
TRIANGLE
= THE
BASE x 1/2 THE PERPENDICULAR HEIGHT.
PARALLELOGRAM
= THE BASE x
THE PERPENDICULAR HEIGHT.
TRAPEZOID
= 1/2 THE SUM OF
THE PARALLEL SIDES x THE PERPENDICULAR
HEIGHT.
CIRCLE
= THE
DIAMETER SQUARED X 0.7854 OR
THE RADIUS SQUARED X 3.1416.
