Dear student,
O is a point in the interior of a given triangle, then three triangles ΔOPQ, ΔOQR, and ΔORP can be constructed. In a triangle, the sum of the lengths of either two sides is always greater than the third side.
(i) Yes, as ΔOPQ is a triangle with sides OP, OQ, and PQ.
OP + OQ > PQ
(ii) Yes, as ΔOQR is a triangle with sides OR, OQ, and QR.
OQ + OR > QR
(iii) Yes, as ΔORP is a triangle with sides OR, OP, and PR.
OR + OP > PR
3 We Know that,
In a triangle sum of two sides is greater than the third side
Hence,In triangle ABM
AB + BM > AM .........1
Also in triangle ACM
AC + MC > AM ..........2
Adding equation 1 and 2 we get,
AB + BM + AC + MC > AM + AM
AB + AC + (BM + MC) > 2AM
AB + AC + BC > 2AM
