Classify Each Quadrilateral and Understand Their Properties

To determine the category of a four-sided figure, focus on the angles and sides. A square has equal-length sides and 90-degree angles. A rectangle shares the 90-degree angle property, but only opposite sides are of equal length. A rhombus, in contrast, has all sides equal but does not require right angles. Finally, a trapezoid, with only one pair of parallel sides, stands apart from these other shapes.

Examine each shape carefully by comparing its angles and side lengths. Check if sides are parallel or if they are of equal length. These factors will guide you in classifying the figure accurately.

By using these clear distinctions, you can easily assign any four-sided figure to its appropriate category. Understanding these basic properties is the first step in mastering the classification of polygons with four sides.
