Which sets of side lengths could form a triangle? choose all that apply a. 3 centimeters,4 centimeters,9 centimeters b. 3 centimeters, 6 centimeters,9 centimeters c. 4 centimeters, 5 centimeters, 9 centimeters d. 4 centimeters, 6 centimeters, 9 centimeters e. 5 centimeters, 5 centimeters, 9 centimeters

To solve this question we will have to make use of the triangle inequality 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".

Let us now use this inequality to check Part A to Part E.

Part A: therefore, triangle is not possible

Part B: therefore, triangle is not possible

Part C: therefore, triangle is not possible

Part D: As all the three sides adhere to the triangle inequality, a triangle is possible with these dimensions.

Part E: As all the three sides adhere to the triangle inequality, a triangle is possible with these dimensions.

Thus, only Options D and E apply
