Q. Can the sides of a triangle have lengths 1, 5, and 8?Choices:(A) yes(B) no
Check Triangle Inequality Theorem: To determine if these can be the sides of a triangle, we need to check the triangle inequality theorem. The sum of the lengths of any two sides must be greater than the length of the third side.
Calculate 1+5: Check if 1 + 5 > 8. Calculation: 1+5=6, which is not greater than 8.
Final Conclusion: Since 6 is not greater than 8, the sides 1, 5, and 8 do not satisfy the triangle inequality theorem. Therefore, they cannot form a triangle.
