Many tiling issues use rectangles, such as tiling the plane with rectangles or tiling a rectangle with polygons. Other geometries, such as spherical, elliptic, and hyperbolic, feature so-called rectangles with equal length opposing sides and equal angles that aren’t right. It’s a type of antiparallelogram with angles that aren’t all right and equal, albeit opposing angles are. The original word rectangle is actually from the Latin word rectangulus, and this word is from the words rectus (right, right) and angulus (angle).Ī crossed rectangle is a quadrilateral with two opposing sides and two diagonals that are self-intersecting (therefore, only two sides are parallel). A square is a rectangle with four equal-length sides. Alternatively, it can be described as an equiangular quadrilateral because all of its angles are equal (360°/4 = 90°), or a parallelogram with those angles. In the Euclidean plane geometry, it is mentioned that a rectangle shape is a quadrilateral with four right angles. What is a rectangle?
