Notes 6-2 properties of parallelograms

Types of Special Parallelograms. First, it is important to note that rectangles, squares, and rhombi (plural for rhombus) are all quadrilaterals that have all the properties of parallelograms. The biggest distinguishing characteristics deal with their four sides and four angles. A rectangle is a parallelogram with four right angles.

If a quadrilateral is a parallelogram, then its opposite angles are congruent. IE: ∠a ≅ ∠c & ∠b ≅ ∠d. Theorem 6-6. If a quadrilateral is a parallelogram, then its diagonals bisect each other.
