Diagonals

The vertices of a polygon that are non – consecutive are joined with the help of a line segment which is termed as a diagonal. The number of diagonals varies according to the number of sides in the given polygon. It is considered as an important characteristic in determining the unique factors of every polygon. These diagonals are also used as an essential factor in numerous formulas and calculations.

Convex Polygons and Concave Polygons

Convex polygons are the figures that are discussed commonly like a triangle, a rectangle, a rhombus. These basically have a defined term and their sides bulge in the outwards direction. In the case of a concave polygon, their sides bulge towards their interior direction. Concave polygons usually do not have set names however they might appear in questions as the complex figures. In this chapter, you will only deal with convex polygons and their characteristics. The exercises also revolve around the convex polygons like rectangle, triangle, quadrilateral, etc.
