Area of a QuadrilateralIntroduction to Polygons

Polygons

Polygons explained with definitions, types, angle properties, and examples to strengthen geometry basics.

1.Introduction to Polygons
Understand the basic idea of polygons, their formal definition, key terms like sides and vertices, and how we name polygons by number of sides with simple examples.
2.Classification of Polygons
Learn how polygons are classified based on sides, shape, and structure—convex, concave, simple, complex, and by number of sides—with clear explanations and examples.
3.Regular and Irregular Polygons
Understand regular and irregular polygons with clear definitions, properties, symmetry, and simple examples explained in a student-friendly way.
4.Interior and Exterior Angles of Polygons
Learn the meaning of interior and exterior angles of polygons, angle sum formulas, and angle properties of regular polygons with clear explanations and examples.
5.Diagonals in Polygons
Learn what diagonals are, how to count them in polygons, formulas for total diagonals and diagonals from a vertex, with clear explanations and examples.
6.Area of Regular Polygons (Basic Cases)
Learn how to find the area of regular polygons such as equilateral triangles, squares, and regular hexagons using simple formulas and diagrams.
