Polygons are closed plane figures with straight sides. They are named according to the number of sides, such as triangle (3 sides), quadrilateral (4 sides), pentagon (5 sides), hexagon (6 sides), and so on. Quadrilaterals form a very important subset of polygons because of their structural properties and wide applications. They can be classified into special types based on symmetry, side lengths, and angle measures. Understanding these properties helps with classification, problem-solving, and practical applications in design, construction, and measurement.
1. Identifies the relationships among various quadrilaterals
Quadrilaterals can be related through their shared properties.
Parallelogram: Opposite sides are parallel and equal in length. Opposite angles are equal, and adjacent angles are supplementary. The diagonals bisect each other but are not necessarily equal. Real-life examples include slanted roof panels, floor tiles arranged in parallelogram shapes, and tables.
