Question

In the figure , PQ = 11 , PR = 61 and QR = 60 complete the following activity to determine whether ∆ PQR is a Q 60 right angled triangle or not ......... PQ = 11 , QR = 60 and PR = 61​

Answer 1

To prove that

We know that,

h² = p²+b²

PR = PQ + QR

61² = 11²+60²

3721 = 121 + 3600

3721 = 3721

So, by this we can say that ∆ PQR is Right Angled at Q. Because PR is it's Hypotenuse.
