Answer:

A, C, D

Step-by-step explanation:

1) A triangular pyramid has the same number of faces as vertices: 5

2) C - The sum is 5 + 6 =11

3) D - Euler's Formula tells us that if we add the number of faces and vertices together and then subtract the number of edges, we will get 2 as our answer.
