A Rhombus is a type of parallelogram. It is a parallelogram with 4 congruent sides A Rhombus is a type of parallelogram. A rhombus has ALL of the qualities of a parallelogram Both pairs of opposite sides are parallel ► ► A rhombus has ALL of the qualities of a parallelogram Both pairs of opposite sides are congruent A rhombus has ALL of the qualities of a parallelogram A pair of opposite sides are both II and ≅ ► ► A rhombus has ALL of the qualities of a parallelogram Both pairs of opposite angles are congruent ◞ ◞ ◝ ◟ ◜ ◜ A rhombus has ALL of the qualities of a parallelogram Diagonals BISECT each other (cut each other in half) A rhombus also has these special properties... All four sides are congruent (the same) A rhombus also has these special properties... Diagonals are perpendicular (form 90 degree angles) A rhombus also has these special properties...
