A square also fits the definition of a rectangle (all angles are 90°), and a rhombus (all sides are equal length). The Rhombus. A rhombus is a four-sided shape where all sides have equal length (marked "s"). Also opposite sides are parallel and opposite angles are equal.
Rectangles have 4 sides and 4 right angles. They all have 2 lines of symmetry (4 lines if they are also a square!) All rectangles belong to the parallelogram family.
In geometry, a polygon is traditionally a plane figure that is bounded by a finite chain of straight line segments closing in a loop to form a closed chain. These segments are called its edges or sides, and the points where two of the edges meet are the polygon's vertices (singular: vertex) or corners.
Polygons are geometric figures of the 2D plane made up of a series of closed segments. The number of segments (called sides or edges) is equal to the number of vertices (or corners) used to define the geometric shape of the polygon.
Each geometric shape has a unique name (ex. rectangle, square, oval, etc) and geometrical shapes can be easily identified by looking at an image and seeing the shape’s characteristics, such as number of sides, angles, curves, or points. In fact, geometric shapes are all around you all of the time.
Let’s have a look at the list of all polygon names and know what they are called. 2D Polygon Shapes 1-100 with Sides and Pictures. Following is a list of polygons 1-100 and their names with the number of sides they have and an example picture.
This is a list of two-dimensional geometric shapes in Euclidean and other geometries. For mathematical objects in more dimensions, see list of mathematical shapes. For a broader scope, see list of shapes.
