Q. Can the sides of a triangle have lengths 3, 4, and 7?Choices:(A) yes(B) no
Check Triangle Inequality: To determine if these lengths can form 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 Sum of Sides: Check if 3 + 4 > 7. Calculation: 3+4=7. Since 7 is not greater than 7, the inequality is not satisfied.
Conclusion: Since one of the conditions of the triangle inequality theorem is not met, these lengths cannot form a triangle.
