Study Notes
Parallelogram
- A quadrilateral where both pairs of opposite sides are parallel.
- Opposite sides are congruent, ensuring equal length.
- Opposite angles are congruent, providing equal angular measures.
- Diagonals bisect each other, indicating they split into equal parts at their intersection.
- Consecutive angles are supplementary, meaning each pair sums up to 180 degrees.
Rectangle
- A specific type of parallelogram with at least one right angle.
- Inherits all properties of parallelograms, ensuring opposite sides are parallel and congruent.
- All angles are right angles, establishing a 90-degree measure for each corner.
- Diagonals of a rectangle are congruent, meaning they are equal in length.
Rhombus
- A unique parallelogram where at least two consecutive sides are congruent.
- All sides are congruent, making it equilateral.
- The diagonals bisect each angle, dividing the angles into two equal parts.
- Diagonals are perpendicular, intersecting at right angles.
- Diagonals divide the quadrilateral into four congruent right triangles.
Square
- A quadrilateral that fulfills the properties of both a rectangle and a rhombus.
- Contains all properties of parallelograms, ensuring parallelism and congruence.
- Mirrors all properties of rectangles, including right angles and congruent diagonals.
- Exhibits all characteristics of a rhombus, including equal side lengths and perpendicular diagonals.
Kite
- A quadrilateral with two distinct pairs of consecutive sides that are congruent.
- Diagonals intersect at right angles, creating additional symmetrical properties.
- One diagonal acts as the perpendicular bisector of the other, ensuring symmetry.
- One diagonal bisects a pair of opposite angles, leading to equal angular measures in those angles.
- One pair of opposite angles are congruent, adding to the overall symmetry.
Trapezoid
- A quadrilateral characterized by one pair of parallel sides, referred to as the bases.
- Non-parallel sides are defined as legs, creating distinction between sides.
- The bases maintain parallelism, impacting the trapezoid's angles and properties.
Isosceles Trapezoid
- A specific trapezoid where the non-parallel sides (legs) are congruent.
- Bases remain parallel, preserving key trapezoidal characteristics.
- Lower and upper base angles are congruent, ensuring symmetry in angular measurements.
- Diagonals are congruent, indicating equal lengths between the two diagonals.
- Each lower base angle is supplementary to the corresponding upper base angle, summing to 180 degrees.
