There are 6, you'd think there would be 8 but the answer is actually 6. A diagonal is a line segment that connects to vertices, the two vertices chosen do not count when forming the triangle, two vertices that are adjacent to that chosen vertex are NOT included when forming the diagonal. It's confusing, but I hope this helps. If you have any follow up questions I'd love to answer them.

Hi there!
The answer is actually D.
Since both the numerator and the denominator multiplied by 3 is 3/9, the answer would be 9.
-1 × 3 = -3
-3 × 3 = -9
Since a negative number times a positive number is a negative number, the correct answer would be D.
Hope this helps!
