The solids that could have resulted in a triangular cross section when cut by a plane parallel to its base include a pyramid, a cone, or a prism with a triangular base.

Step 1: Consider the shape of the cross section, which is a triangle.
Step 2: Think about which three-dimensional shapes would result in a triangular cross section when cut parallel to their base.
Step 3: Conclude that a pyramid, a cone, or a prism with a triangular base would all result in a triangular cross section when cut in this way.
