           SUBTOPICS: Equilateral and Isosceles triangle


           1. Is it possible to have a triangle with the following sides?
               2 cm, 3 cm, 5 cm

           2. Take any point O in the interior of a triangle PQR. Is
           (i) OP + OQ > PQ?
           (ii) OQ + OR > QR?
           (iii) OR + OP > RP?

           (iii) OR + OP > RP?














           3. ABCD is quadrilateral.
           Is AB + BC + CD + DA < 2 (AC + BD)?











           4. The lengths of two sides of a triangle are 13 cm and 17 cm. between what two measures
           should the length of the third side fall?
