Concept:A triangular prism has two triangular bases and three rectangular sides. The vertices are the corners where edges meet.Explanation:Each triangular base has 3 vertices, so two bases give 3 + 3 = 6 vertices in total.The rectangular faces do not add extra vertices because they share the same corner points with the triangles.Counting all corners: the top triangle has 3 vertices, the bottom triangle has 3 vertices, and no other corners exist.Thus, a triangular prism has 6 vertices.
