text: A parallelogram where all angles are right angles is a rectangle!
text: If the parallelogram is a rectangle, the two diagonals are of equal lengths (AC) = (BD), so
text: Move that cut off triangle over to the right side and the parallelogram is suddenly a rectangle.
text: The following statement is valid: If a parallelogram is a rectangle, then its diagonals are equal in length.
text: Vice versa, if the diagonals of a parallelogram are equal in length, then this parallelogram is a rectangle.
text: Remember, for a parallelogram to be a rectangle is must have four right angles,

text: Yes, all rectangles are parallelograms, but not all parallelograms are rectangles.
text: A quadrilateral with equal sides is called a rhombus, and a parallelogram whose angles are all right angles is called a rectangle.
