Symbols definition of ABC triangle

You have entered sides a, b, and c.

Entered triangle sides do not satisfy the triangle inequality. The triangle cannot be constructed and therefore solved.

a = 40
b = 10
c = 55

a+b ≤ c
40 + 10 ≤ 55
50 ≤ 55

The sum of the lengths of sides a, b must be greater than the length of the remaining side c.
