What is a polygon in geometry?

polygon, in geometry, any closed curve consisting of a set of line segments (sides) connected such that no two segments cross. The simplest polygons are triangles (three sides), quadrilaterals (four sides), and pentagons (five sides).

Similarly, How many sides is a polygon? Triangles, quadrilaterals, pentagons, and hexagons are all examples of polygons. The name tells you how many sides the shape has. For example, a triangle has three sides, and a quadrilateral has four sides .

  2. Get your students to count the sides and corners.
  3. Ask if the sides are the same length on both shapes. …
  4. Emphasize that shapes with 5 sides are pentagons, but if the sides and corners are not equal it is an irregular pentagon.
