What is the shape of the cross section of the triangular prism in each statement?
1. A triangular prism is sliced so the cross section is parallel to the base.
Options: circle, triangle, trapezoid, or rectangle
2. A triangular prism is sliced so the cross section is perpendicular to the base.
Options: circle, triangle, trapezoid, or rectangle
Thanks so much!

Your question does not state which side it is calling the base! Therefore there can be no definitive answers!
Whoever wrote this multiple choice question should be given a stern talking to. LOL
You need to specify whether you are calling the base a triangle or a rectangle.
Then you can answer these questions yourself.
If you post your answers someone will tell you if they are right. (I will if I see your post)

Here are some pictures of some triangular prisms
My teacher asked this question, I apologize. The base of the triangular prism is going to be a rectangle.
Parallel to the base would be a triangle.
Perpendicular to the base would be a rectangle.
Right?

You are right, it certainly cannot be a trapezoid or a circle :)
If the base is a rectangle and you chop it parallel to the base, that means in the same direction as the base, (sideways) then you will get smaller and smaller rectangles. Can you see that?
If you chop it perpendicular to the base, that is like the chocolates in a toblerone bar are divided, then each cros section will be a triangle, exactly the same as the triangle at the front. :)
Think about it :)
+9465 This image may help. To look at a cross section, imagine slicing through it with a knife, and look at the shape you just formed from the slicing.
Also, I have a tip for how to remember parallel from perpendicular.
The two L's in " Parallel " are two parallel lines! 
To Melody, I have a question...aren't there two ways to get a perpendicular cross section???
