Question

Which of the following side lengths can form a triangle?

Answer 1

To be a triangle every side has to be smaller than the other two added together, otherwise it would collapse to a line

100+200<600 -> can't be a triangle

11+14<26 -> can't be a triangle

10+16<30 -> can't be a triangle

41+51>61
41+61>51
51+61>41
-> is a triangle

4)

20+34>27
20+27>34
34+27>20
-> is a triangle

20+34<=60 -> not a triangle

14+20<=34 -> not a triangle

20+34<=54 -> not a triangle

5)
52+70<=122 -> not a triangle

52+70>124
52+124>70
70+124>52
->is a triangle

52+70>11
52+11<70 -> not a triangle

52+16<70 -> not a triangle
