To determine if three side lengths \( a \), \( b \), and \( c \) can form a triangle, they must satisfy the triangle inequality theorem, which comprises three conditions:

  1. \( a + b > c \)
  2. \( a + c > b \)
  3. \( b + c > a \)

From your statement, it seems you’re focusing on specific conditions related to \( a \). Here they are completed:

  1. \( a < b + c \)
  2. \( a > |b - c| \) (this corresponds to the condition \( a > b - c \) when \( b \) is greater than \( c \), and it also provides the lower bound for \( a \) based on triangles).

So, the complete conditions are:

  • \( a < b + c \)
  • \( a > |b - c| \)

This ensures that the lengths \( a \), \( b \), and \( c \) can form a triangle.
