Answer 1

You have to verify Pythagoras theorem here,

(I) PQ^2 + QR^2 = PR^2

(8)^2 + (6)^2 = (10)^2

64 + 36 = 100

100 = 100

Therefore, it is a right angled triangle.

(ii) A^2 + BC^2 = AC^2

(4)^2 + (3)^2 = (5)^2

16 + 9 = 25

25 = 25

Therefore, it is a right angled triangle

Answer 2

By Pythagoras property
