PARALLELOGRAM Meaning and
Definition
-
A parallelogram is a geometric figure that represents a quadrilateral with two pairs of parallel sides. It is a four-sided polygon with opposite sides that are parallel, meaning they never intersect. In addition to the parallel sides, a parallelogram also has opposite angles that are congruent, or equal in measure. The sum of the interior angles of a parallelogram is always 360 degrees.
The basic properties of a parallelogram include symmetry, where one half is a mirror image of the other half. It also exhibits rotational symmetry, meaning it can be rotated by 180 degrees and still maintain its original shape and measurements. Furthermore, a parallelogram has diagonals that bisect each other and create four congruent triangles within.
Parallelograms have various types, including rectangles, squares, and rhombuses. A rectangle is a parallelogram with all angles measuring 90 degrees, while a square is a parallelogram with all angles measuring 90 degrees and all sides of equal length. A rhombus is a parallelogram with all sides of equal length.
The practical applications of parallelograms can be seen in architecture, engineering, and design fields. They serve as building blocks in creating stability and balance in structures. In mathematics, parallelograms are often used in calculating areas and solving geometric problems.
