Statement I: True. The perimeter of any triangle exceeds the sum of its medians. This is a fundamental geometric property applicable to all triangle types.
Statement II: Also true. This is a triangle inequality for a point within the triangle. If D is on side BC, the sum of distances AD, BD, and CD always surpasses the length of any triangle side. This inequality applies universally and is a core geometric result.
In the figure O is the centre of the circle and A, B, C are points on the circle. AOB = 50^, BOC = 80^.
