Proving that Figures are Special Quadrilaterals.
... In order to prove this quadrilateral to be a rectangle, one side must be right. A right angle is 90 degrees, therefore, the measurements of each angle must be added together and set equal to 90 degrees. Then the value of X must be found. In order for this quadrilateral to be a rectangle, the value o ...
