Worked Solution

Step 1: Identify the faces of a triangular prism. A triangular prism has 5 faces: 2 triangular faces (at the two ends) and 3 rectangular faces (along the length). Step 2: Identify which face is at the top. The prism rests on one rectangular face. The face directly on top (opposite the base) is also a rectangular face. Step 3: Determine the top view. The top view is the 2D outline seen when looking straight down from directly above. The topmost face is a rectangle, so the top view is a rectangle. Answer: Rectangle

Correct answer: Rectangle
