Special quadrilaterals are a subset of four-sided polygons with unique properties such as congruent sides and angles, parallel sides, and specific symmetry
Special quadrilaterals are notable for their regularity and symmetry, which are central to the study of their geometric properties
The term "quadrilateral" originates from the Latin words "quadri" (four) and "lateral" (sides), referring to a geometric figure with four edges and four vertices
The rectangle is a special quadrilateral with opposite sides that are equal in length and parallel, and four interior right angles
The square is a special quadrilateral with all four sides and angles being equal, and diagonals that bisect each other at right angles
The rhombus is a special quadrilateral with all four sides being equal, opposite sides running parallel, and diagonals intersecting at right angles
The trapezoid is a special quadrilateral with one pair of parallel sides (bases) and the sum of interior angles adjacent to each base being 180 degrees
The kite is a special quadrilateral with two pairs of adjacent sides being congruent, and diagonals intersecting at right angles
The area and perimeter of special quadrilaterals can be calculated using specific formulas based on their properties, such as the length of sides and diagonals
The area of a rectangle is found by multiplying the length by the width, and the perimeter is the sum of all sides
The area of a square is the length of a side squared, and the perimeter is four times the side length
The area of a rhombus is half the product of the lengths of its diagonals, and the perimeter is the sum of all sides
The area of a trapezoid is calculated as half the product of the sum of the lengths of the bases and the height, and the perimeter is the sum of the lengths of all sides
The area of a kite is half the product of the lengths of the diagonals
