Read Step 3 from "How to Make a Paper Airplane.”
Step 3. Then open the paper and lay it in front of you again. The folded corners should be at the top, farthest away from you. Make sure you can see the folded corners.
Your paper won’t be a rectangle anymore. Instead, the paper should be shaped like a triangle sitting on top of a rectangle. You should now have something that looks a little like a house a child might draw. There’s a point at the top and then a "roof” that slopes down to straight sides.
What should the paper look like at the end of step 3 according to the procedure described?
a boat
a pyramid
a house
a bridge
