Geometry Level 3

Above is an image of regular loops joined together at right angles.

What shape do we get after cutting along the dashed lines?

Details and Assumptions:

A half twist is a \(180^{\circ}\) rotation of one side of the paper before you stick them together.
We define a twisted loop to be a loop with a positive even number of half twists.
