B. triangle 1, triangle 2, and triangle 3
C. triangle 1 and triangle 3
D. triangle 1, triangle 3, and triangle 4

Triangle 1 and 4

Step-by-step explanation: It's not in the options, but it's definitely 1 and 4 because they both a 70 degree acute angle from the left. I think the multiple choice options could be wrong.

Triangles 1 and 4

Step-by-step explanation:

You see that the line markings are in the same areas

The size is the same

there is an angle on the bottom that says 70˚. It is on both triangles.

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
