Answer

False Explanation 1. Check Triangle Inequality Theorem For a set of lengths to form a triangle, the sum of any two sides must be greater than the third side. Check all combinations: - 2 + 8 > 5 (True) - 2 + 5 > 8 (False) - 8 + 5 > 2 (True) 2. Determine Validity Since one condition is false (2 + 5 \not> 8), these lengths cannot form a triangle.

Explanation

1. Check Triangle Inequality Theorem<br /> For a set of lengths to form a triangle, the sum of any two sides must be greater than the third side. Check all combinations:<br />- $2 + 8 > 5$ (True)<br />- $2 + 5 > 8$ (False)<br />- $8 + 5 > 2$ (True)<br /><br />2. Determine Validity<br /> Since one condition is false ($2 + 5 \not> 8$), these lengths cannot form a triangle.
