Quadrilateral Properties Chart Flashcards

Parallelograms feature 2 pairs of opposite sides that are parallel, contributing to their unique properties.
Trapezoids have at least 1 pair of opposite sides that are parallel, distinguishing them from other quadrilaterals.
Congruent Sides are a hallmark of many quadrilaterals: both pairs of opposite sides in parallelograms, rectangles, rhombuses, and squares are congruent.
Adjacent Side Congruence is characteristic of rhombuses, squares, and kites, where 2 pairs of adjacent sides are equal.

Isosceles Trapezoids are defined by having exactly 1 pair of congruent sides, which is a key identifying feature.
All Sides Congruent quadrilaterals include rhombuses and squares, with kites occasionally falling into this category.

Opposite Angles are congruent in parallelograms, rectangles, rhombuses, and squares, showing symmetry in their structure.
Kites are unique as they have exactly one pair of congruent angles, setting them apart from other quadrilaterals.
Right Angles are exclusive to rectangles and squares, both of which have all angles measuring 90 degrees.

Diagonal Bisection occurs in parallelograms, rectangles, rhombuses, and squares, ensuring that diagonals divide each other equally.
Congruent Diagonals can be found in rectangles, squares, and isosceles trapezoids, indicating regularity in shape.
Perpendicular Diagonals are a notable trait of rhombuses, squares, and kites, often creating distinct angle relationships.

Kites feature one diagonal that bisects the other.
Rhombuses and Squares have diagonals that bisect both pairs of opposite angles, illustrating their symmetry and balance.

Supplementary Angles are a characteristic of parallelograms, rectangles, rhombuses, squares, trapezoids, isosceles trapezoids, and sometimes kites, ensuring that adjacent angles sum to 180 degrees.
