**1. What is the Angle Sum of Property in Quadrilateral?**

When a diagonal is drawn in a quadrilateral, it splits it into two triangles. And it is known that the angle sum property of a triangle i.e. if we add up all three angles of a triangle, it will be 180°. Suppose there is a quadrilateral with sides PQRS. Then the sum of angles of ∆PSR= 180°. The sum of angles of ∆PQR = 180°. By adding both we get, ∠P + ∠Q + ∠R + ∠S = 360°. Thus, we know that the sum of the four angles of a quadrilateral is 360°.

**2. What are the types of Quadrilaterals?**

There are five types of Quadrilaterals:

**Rectangle**- has every angle 90°.**Square****Parallelogram****Rhombus****Trapezium**

**3. What is the importance of Quadrilaterals in our day to day life?**

There are numerous ways in which quadrilaterals are used in real life. Square shapes are frequently applied for uniformity they're effortless to tessellate or design with. Same with diamonds or blocks. Figures like trapeziums with a broad foothold and a slim top are applied for construction or building. Shapes like buses or other abnormal quadrilaterals are applied for design to make stuff appear good and the eye notices because it isn't unwavering.
