Geometry: Parallelograms and Special Quadrilaterals

Study Notes

Parallelogram

Opposite angles are congruent, maintaining symmetry across the shape.
Opposite sides are congruent, ensuring equal length and stability.
Diagonals bisect each other, creating two pairs of equal triangles within the structure.
Consecutive angles are supplementary, meaning their measures combine to 180 degrees.

Rectangle

Inherits all properties of a parallelogram, emphasizing its classification.
Diagonals are congruent, offering a unique attribute not found in all parallelograms.
Adjacent sides are perpendicular, resulting in four right angles in this quadrilateral.

Rhombus

Incorporates all parallelogram properties, underscoring its classification.
Features four congruent sides, ensuring uniformity in length.
Diagonals bisect the angles they intersect, creating equal angles at the vertices.
Diagonals are perpendicular to each other, forming right angles at their intersection.

Square

Embodies all properties of parallelograms, rectangles, and rhombuses, making it the most specialized quadrilateral.
Represents a perfect blend of equal sides and right angles.

Kite

Distinguished by having adjacent sides that are congruent, unlike many other quadrilaterals.
Diagonals are perpendicular, forming right angles at their intersection.
One diagonal bisects the other, creating an asymmetrical division.

Trapezoid

Characterized by having one pair of parallel sides, giving it a unique structural feature among quadrilaterals.

Isosceles Trapezoid

Contains one pair of parallel sides, defining its basic structure.
Features one pair of congruent sides, enhancing its geometric symmetry.
Diagonals are congruent, providing additional balance and aesthetic appeal.
