I. $$a^2 = b^2 + c^2$$
II. $$a < b + c$$

I. The radius of the field is half of its diameter.
II. The diameter of the field is 200 mts and the cost of fencing is Rs. 10 per meter.
In a triangle $$ABC, \angle B = 90^\circ$$. Then what is $$AB : BC : CA ?$$
I. $$\tan C = \frac{1}{2}$$
II. $$\sin^2 A + \cos^2 A = 1$$
