FAQs on RD Sharma Class 9 Solutions Chapter 14 - Quadrilaterals (Ex 14.2) Exercise 14.2
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 - has all equal sides and each angle is 90°.
Parallelogram - has both the pairs of opposite sides are parallel.
Rhombus - Has all equal sides.
Trapezium - has one opposite side pair that is parallel.
3. What is the importance of Quadrilaterals in our day to day life?
