Question

Apply the Triangle Inequality Theorem to determine which three side lengths form a triangle.
(1 point)
A. 8, 8, 20
B. 8, 4, 12
C. 20, 10, 30
D. 10, 20, 15

Pick one answer

Answer 1

B. 8, 4, 12

Using the Triangle Inequality Theorem, we can see that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

In this case, 8 + 4 is greater than 12, 8 + 12 is greater than 4, and 4 + 12 is greater than 8. Therefore, the side lengths 8, 4, and 12 can form a triangle.
