Step-by-step explanation:
If a ≤ b ≤ c is the length of the sides, then a + b > c.
(a)
We have a = 3cm, b = 4cm, c = 6cm.
Check:
a + b = 3cm + 4cm = 7cm
c = 6cm
7cm > 6cm → a + b > c CORRECT :)
YES. It's possible.
(b)
We have a = 1cm, b = 3cm, c = 4cm
Check:
a + b = 1cm + 3cm = 4cm
c = 4cm
4cm = 4cm → a + b = c
NO. It's impossible.
