It is possible for a square to be a rectangle, but it is impossible for a rectangle to be a square. In order to be a square, the shape must contain four straight sides with 90-degree angles that are all the same length.
Know MoreA rectangle has four straight sides with four right angles, but the sides can be different lengths. The opposite sides of a rectangle must be parallel with one another and feature equal lengths. This means the shape can be tall and skinny or short and fat. The sides on a square must all be parallel in comparison with one another.
Learn MoreTessellations occur when a shape is repeated in an interlocking pattern that fully covers a flat surface, or plane, like the pieces of a puzzle. Some shapes cannot tessellate because they are not regular polygons or do not contain vertices (corner points). They therefore cannot be arranged on a plane without overlapping or leaving some space uncovered. Due to its rounded edges and lack of vertices, the circle is normally not tessellated.
