# Take any point O in the interior of a triangle PQR. Is

(i) OP + OQ > PQ?

(ii) OQ + OR > QR?

(iii) OR + OP > RP?

**Solution:**

If 'O' is a point in the interior of a given triangle, then the three triangles can be constructed.

You must join all the three vertices of a triangle with the center 'O'.

This question is based on a property that in a triangle the sum of lengths of any two sides is always greater than the third side.

i) Yes, POQ forms a triangle and we know that in a triangle the sum of lengths of any two sides is always greater than the third side.

Thus, OP + OQ > PQ

ii) Yes, OQR forms a triangle and we know that in a triangle the sum of lengths of any two sides is always greater than the third side.

Thus, OQ + OR > QR

iii) Yes, ORP forms a triangle and we know that in a triangle the sum of lengths of any two sides is always greater than the third side.

Thus, OR + OP > RP
