Q. Can the sides of a triangle have lengths 1, 1, 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.
Check Side Lengths: Check if 1 + 1 > 8. Calculate 1+1=2. Since 2 is not greater than 8, the sides 1, 1, and 8 do not satisfy the triangle inequality theorem.
