Angle sum property in a quadrilateral
A quadrilateral has four sides, four angles and four vertices.
In this chapter, we will study more about different types of quadrilaterals, their properties and especially those of parallelograms.
In this video, we learn how to apply Congruency Rule to solve Problems on Qudrilaterals. Use parallel lines concept and triangle congruence theorems to prove/solve problems on properties of parallelograms.
