Final Jeopardy

What are the similarities and differences
between parallelograms and rectangles?

A rectangle is a parallelogram. Therefore has all the properties of a
parallelogram: opposite sides parallel, opposite sides congruent,
opposite angles congruent, consecutive angles supplementary and
diagonals bisect each other. In addition, a rectangle has four
congruent right angles and congruent diagonals.
