To determine if three side lengths \( a \), \( b \), and \( c \) can form a triangle, the triangle inequality theorem must be satisfied. The conditions can be stated as follows:
- \( a < b + c \) (the length of one side must be less than the sum of the lengths of the other two sides)
- \( a > |b - c| \) (the length of one side must be greater than the difference of the lengths of the other two sides)
Thus, you can complete your statements as:
- \( a < b + c \)
- \( a > b - c \) (or equivalently \( a > |b - c| \) to cover the absolute value)
So, the full conditions are:
- \( a < b + c \)
- \( a > |b - c| \) (which encompasses both \( a > b - c \) and \( a > c - b \)).
