What is the same about a parrallelogram and a rectangle?
-- four sides -- four angles -- opposite sides are equal -- opposite sides are parallel -- opposite angles are equal -- adjacent angles are supplementary -- sum of interior angles is 360 degrees -- sum of exterior angles is 360 degrees -- area = (length of the base) x (height) -- can always be formed with two triangles -- diagonals bisect each other
