Question

Which three lengths could be the lengths of the sides of a triangle?
6 cm, 23 cm, 11 cm
10 cm, 15 cm, 24 cm
22 cm, 6 cm, 6 cm
15 cm, 9 cm, 24 cm
Can someone explain this to me please?

Answer 1

In any given triangle, if the sides are a, b and c, then:
\(\Large \color{MidnightBlue}{\Rightarrow a + b>c }\)
\(\Large \color{MidnightBlue}{\Rightarrow b + c>a }\)
\(\Large \color{MidnightBlue}{\Rightarrow a + c>b }\)

Answer 2

The second one qualifies :)
