If the front view and top view of a triangular prism with equal edge lengths are square and regular triangle respectively, then the left view is () A. Rectangle B. square C. diamond D. regular triangle

If the front view and top view of a triangular prism with equal edge lengths are square and regular triangle respectively, then the left view is () A. Rectangle B. square C. diamond D. regular triangle

The height of the left view of the triangular prism must be the edge length, and the width is equal to the height of the regular triangle in the top view. This height must be less than the edge length, so the left view is rectangular. So select a
