Just make some 1:10 scale models and play with them. Or better yet, just play with a few pieces of paper and see if you can “fit” them into a shape. Then consider *generally* why things fit or didn’t fit. How could you describe how you tilted them mathematically?

Don’t forget your Pythagorean theorem!

Hint: if you tilt an object to fit through a door, does the object need to be the same width or smaller than the door, or does something else need to be the same width or smaller?
