The hexagonal cells in a honeycomb or diamond shape pattern on a snakeskin are natural examples of tessellation.ġ. Only rectangular hexagons, equilateral triangles and squares can make regular tessellations. The dimension of the plane figure is length and breadth.Ī tessellation is created when a particular shape is repeatedly made without any overlapping or gaps and it covers a plane. The dimension of a solid figure is length, breadth and height. Triangle: A polygon with three sides and three angles is known as a triangle. Plane shapes include squares, rectangles, triangles, circles, pentagons, octagons, hexagons, ovals etc. They are also known as plane geometric figures or polygons. If we closely observe a sheet of paper, our observation would be on its length and width but no depth, so they are closed shapes as they are made by joining either two straight lines or curved lines. Some basic plane shapes are triangles, squares, rectangles, circles and ovals. Instead of edges and faces, they possess several light lines that make a corner or a vertex where the two straight lines meet. In contrast to solid shapes, a closed two-dimensional or flat surface figure is known as a plane shape. A grouping of shapes is called polygons, like squares and rectangles, but circles and ovals are not polygons. Plane figures include squares, rectangles, triangles, circles, pentagons, octogen, hexagons, ovals etc. Imagine a wall and extend it infinitely, it becomes a plane. A plane has nothing but a surface with no thickness or width. Two planes can be parallel to each other, can be identical and can intersect each other. In algebra, the points are plotted in the coordinate plane which has a number line extending left to right and upwards and downwards endlessly and infinitely. In the real world, there is no object that represents a plane figure.Ī plane is a two-dimensional surface measured by two linearly independent points a plane doesn't have an obvious direction and can extend indefinitely. ![]() Any shape that is drawn on paper is known as a plane figure. The thickness of the plane figure is zero. A plane figure is known as a 2-dimensional shape because it has only length and breadth. ![]()
