    pi = 3.141....

22/7 = 3.142

the difference is = 0.001...........

22/7 is > pi  

pi = 22/7 is accepted all over the world (perhaps being equal upto two decimal places  3.14)

circumference / diameter = 2 x pi x r / d = 2 x pi x r / 2r = pi      (as diameter = 2 x radius)

first time the ratio was calculated by Greece and denoted by the letter pi

right angle              that is = 90o exactly                                    90o

obtuse angle           greater than 90o but less than 180o        120o , 95o

In ΔPQS
Sum of any two sides is greater than the third side.
So, PQ + QS > PS ......(1)

In ΔPSR
Sum of any two sides is greater than the third side.
So, PR + SR > PS ...(2)

Adding equations (1) and (2)

PQ + PR + QS + SR > PS + PS

PQ + PR + QR > 2PS   [ QS + SR = QR]
