Understanding Quadrilaterals

In this topic, we will discuss polygons. A polygon is a closed figure that at least three sides or more. Polygons are named according to the number of sides and angles they have. For example, triangle, rectangle, etc.

This topic gives an account of the classification of polygons based on the number of sides they have. These figures are explained well with proper illustrations to make us grasp the basics quickly.

This topic states that the sum of the measures of the external angles of any polygon is 360 degrees. We can find a number of sides of a regular polygon with the given angle. We can find the number of the sides by dividing the exterior with 360 degrees.

This topic explains the types of quadrilaterals based on the nature of the sides or angles of a quadrilateral. Those are trapezium, kite, parallelogram, etc. A parallelogram is a quadrilateral whose opposite sides are parallel.

This topic talks about the elements, angles and diagonals of parallelograms with the aid of illustrations. Some properties of the paralellograms will also be enumerated here.

This topic discusses some special parallelograms. They are rhombus, rectangle and square. In a parallelogram, the diagonals can be of different lengths but the rectangle has diagonals of equal length.
