Question 17
AI reconstruction. For this reconstructed view, take the lower/front vertex of the pictured tetrahedral pencil frame as the raised vertex. Project it to the center of the triangle formed by the other three vertices. Keep the original upper vertex at the top of the answer triangle and the original left and right vertices at its lower corners. Which diagram preserves the color of every edge? Compare red versus blue only: explicitly ignore the pointed-end directions, which the answer drawings do not preserve faithfully.
