Question

Give reason to show that the construction of ∆PQR is not possible : PQ = 7 cm

Answer 1

hey

______

construction is not possible

given : PQ = 7cm

PR=4cm

QR=3cm

the sum of three sides of a ∆ is always greater than the third sides

4+3 = 7

7=7 (here sum of two sides is equal to third side)

7+3 = 10

10>4 (sum of two sides is greater than third)

4+7=11

11> 3 ( sum of two sides is greater than third)

hence all the cases are not true and construction is not possible

hope helped
