CBSE Class 9 Answered

Ajay was asked to find the sum of the four angles of a quadrilateral. He found the sum of the four angles as 270o by giving the reasoning as follows: Sum of the three angles of a traingle [made up of three sides] = 2 right angles = (3-1) right angles. So, sum of the four angles of quadrilateral [made up of four sides] = (4 – 1) right angles = 3 right angles = 270o His classmate Anju pointed out that the sum obtained is incorrect and found the correct sum. Ajay accepted his mistake and thanked Anju for the same. Write the correct solution. What value is depicted from this action?
