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.
