The name of the plane is Quadrilateral. A quadrilateral is a four-sided polygon with specific vertices and angles, such as rectangles and parallelograms. The sum of its interior angles equals 360 degrees
A quadrilateral is a geometric figure consisting of four straight sides and four vertices, forming four angles. It belongs to the broader category of polygons, and its defining characteristic is the presence of exactly four sides. Each vertex is a point where two adjacent sides meet, and the angles enclosed by these sides determine the quadrilateral's overall shape. The sum of the interior angles of any quadrilateral is invariably 360 degrees, a fundamental property derived from Euclidean geometry.
Various types of quadrilaterals exist, each exhibiting distinct characteristics. Rectangles, for instance, possess right angles, while squares are a special case of both rectangles and rhombi, featuring equal sides and right angles. Parallelograms, on the other hand, have opposite sides that are both equal and parallel. These diverse forms showcase the versatility of quadrilaterals in geometry and mathematics.
