Which of the following possibilities will form a triangle?
Side = 10 cm, side = 5 cm, side = 6 cm
Side = 10 cm, side = 6 cm, side = 3 cm
Side = 11 cm, side = 5 cm, side = 6 cm
Side = 11 cm, side = 5 cm, side = 5 cm

make sure that the sum of the two shorter sides is longer than the longest side
OpenStudy (anonymous):
for example 2 is out since \(6+3=9\) and \(9<10\)

OpenStudy (anonymous):

OpenStudy (anonymous):
