Polygon Geometry

If three or more line or line segment formed a closed shape, then it is known as a polygon. Consider all the sides of polygon are a line or line segments and each side of the line must intersect exactly two others sides but only at their endpoints. The sides of the polygon must be non-collinear and have a common endpoint. If one of the sides of a closed shape is a curve then it not consider as a polygon.


All the geometric shapes are classified based on the number of sides.

  • Triangle (3-sides): Triangles are a three-sided polygon that consists of three edges and three vertices.

    Here Three Sides are AB, BC, CA.
    Here three vertices are ∠ABC, ∠BCA, ∠CAB.

  • Quadrilateral (4-sides): A polygon or 2D geometric shape has four sides or edges and four corners or vertices.

    Here four sides are AB, BC, CD, DA.
    Here four vertices are ∠ABC, ∠BCD, ∠CDA, ∠DAB.

  • Pentagon (5-sides)
  • Private Teacher
  • Hexagon (6-sides)
  • Heptagon (7-sides)
  • Octagon (8-sides) and so on.

Here we are discussing all about Triangle and Quadrilateral.
