2. PROPERTIES --Sum of all interior angles = 360 --Opposite angles are congruent --Opposite sides are congruent & parallel --Diagonals divide parallelogram into two congruent triangles --Diagonals bisect each other --Sum of all exterior angles = 360 --Two consecutive angles are supplementary = 180
3. A Square is a parallelogram with all congruent sides. PROPERTIES -- Opposite angles are congruent -- All angles = 90 -- Diagonals bisect each other -- Diagonals are perpendicular -- Opposite angles are congruent -- Sum of all interior & exterior angles= 360 -- Consecutive angles are supplementary =180 -- One diagonal cuts square into 2 congruent triangles
4.
5. PROPERTIES -- Diagonals bisect each other -- Opposite sides -congruent -- Opposite angles -- Consecutive angles are supplementary= 180 -- Exterior & Interior angles = 360 -- Diagonals cut a rectangle into two congruent triangles -- all properties of parallelogram -A Rectangle is a parallelogram with right angles .
