Q. Can the sides of a triangle have lengths 2, 7, and 7?Choices:(A) yes(B) no
Check Triangle Inequality Theorem: Check if the given side lengths satisfy the triangle inequality theorem. The theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.Calculation: 2+7=9, which is greater than 7.
Verify Other Combinations: Check the other two combinations of side lengths.Calculation: 7+7=14, which is greater than 2.
Final Side Length Calculation: Check the last combination of side lengths.Calculation: 2+7=9, which is greater than 7.
