Q. Could 10.6cm,5.6cm, and 4.0cm be the side lengths of a triangle?Choose 1 answer:(A) Yes(B) No
Check Triangle Inequality Theorem: To determine if three lengths can form a triangle, we use the Triangle Inequality Theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. We will check this for all three combinations of sides.
Calculate Sum of Two Shorter Sides: First, we check if the sum of the two shorter sides, 5.6cm and 4.0cm, is greater than the longest side, 10.6cm. We calculate 5.6+4.0 and compare it to 10.6.
Verify Theorem Not Satisfied: The sum of the two shorter sides is 5.6+4.0=9.6cm, which is not greater than the longest side, 10.6cm. This means that the Triangle Inequality Theorem is not satisfied.
Conclusion: Since the sum of the lengths of the two shorter sides is not greater than the length of the longest side, the lengths 10.6cm, 5.6cm, and 4.0cm cannot form a triangle.
