6-5 Rhombi and SquaresN#____ ____/____/____ SLG : Students will be able to recognize and apply the properties of rhombi and squares. They will also be able to determine if a parallelogram is a rhombus or square.
A parallelogram with all four congruent sides R H Rhombus: Every rhombus has all of the properties of parallelograms; opposite sides parallel, opposite sides congruent, opposite angles congruent, consecutive angles supplementary, diagonals bisect each other. M O
Properties of a Rhombus: • Opposite sides parallel. • Opposite sides congruent • Opposite angles congruent. • Consecutive angles supplementary. • Diagonals bisect each other. Parallelogram All four sides are congruent Rhombus Diagonals are perpendicular Diagonals are angle bisectors
A parallelogram with all four congruent sides and four right angles S Q Square: Since a square has 4 right angles, a square is a rectangle. Since a square has 4 congruent sides, a square is a rhombus. A U
Properties of a square: • Opposite sides parallel. • Opposite sides congruent. • Opposite angles congruent. • Consecutive angles supplementary. • Diagonals bisect each other. Parallelogram All four angles are right angles Rectangle Diagonals are congruent All four sides are congruent Diagonals are perpendicular Rhombus Diagonals are angle bisectors
