Study Notes
Properties of Quadrilaterals
- Quadrilaterals are four-sided polygons, characterized by their interior angle sum of 360 degrees.
Types of Quadrilaterals
- Rectangle: A parallelogram where at least one angle measures 90 degrees.
- Square: A specific type of parallelogram that is both a rectangle (all angles 90 degrees) and a rhombus (all sides equal).
- Kite: A quadrilateral with two sets of adjacent sides that are congruent, forming a distinct shape.
- Parallelogram: A quadrilateral with both pairs of opposite sides parallel.
- Trapezoid: A quadrilateral featuring exactly one pair of parallel sides, known as the bases.
- Isosceles Trapezoid: A trapezoid where the non-parallel sides are of equal length.
- Rhombus: A parallelogram with at least two consecutive sides that are equal in length.
Properties of Specific Quadrilateral Types
-
Parallelogram Properties:
- Opposite sides are equal in length.
- Opposite angles are equal.
- Diagonals bisect each other.
- Consecutive angles are supplementary (add up to 180 degrees).
-
Rhombus Properties:
- Inherits all properties of parallelograms.
- Diagonals intersect at right angles.
- Diagonals bisect opposite angles.
-
Rectangle Properties:
- Inherits all properties of parallelograms.
- Diagonals are equal in length.
-
Square Properties:
- Inherits all properties of parallelograms, rhombuses, and rectangles.
-
Trapezoid Properties:
- Two sets of consecutive angles are supplementary.
-
Isosceles Trapezoid Properties:
- Inherits all trapezoid properties.
- Opposite angles are supplementary.
- Base angles are equal.
- Diagonals are equal.
-
Kite Properties:
- Diagonals intersect perpendicularly.
- One pair of opposite angles are equal.
- The long diagonal bisects the short diagonal and the opposite angles.
Relationships Among Quadrilaterals
- Quadrilaterals that have opposite sides parallel include parallelogram, rectangle, rhombus, and square.
- Quadrilaterals with only one pair of parallel sides are trapezoid and isosceles trapezoid.
- Those with opposite sides congruent are parallelogram, rectangle, rhombus, and square.
- Quadrilaterals where consecutive angles are supplementary include parallelogram, rectangle, rhombus, and square.
- A kite is uniquely defined by having two pairs of disjoint consecutive sides that are congruent.
- Opposite angles being congruent applies to parallelogram, rectangle, rhombus, and square.
- Only kites have exactly one pair of opposite angles that are congruent.
- Shapes with all angles right angles are rectangles and squares.
- Rhombuses and squares are defined by having all sides equal in length.
- Diagonal congruence applies to rectangles and squares only.
- Diagonals that bisect each other are a feature of parallelogram, rectangle, rhombus, and square.
- Perpendicular diagonals are characteristic of rhombus, square, and kite.
- A kite is defined by having diagonals that are perpendicular, with one diagonal bisecting the other.
- A square is the only quadrilateral where diagonals are congruent, perpendicular, and bisect each other.
- Rhombus and square diagonals bisect opposite angles, while kites feature one diagonal that bisects a pair of opposite angles.
