Frivolous Matchstick Puzzles

Looking at some of the comments in the other Matchstick Puzzles posts, it seems like people like to bend the interpretation of these puzzles. So, here are some questions which you should try an answer unconventionally.

You may work in 3-D, layer matchsticks over each other, or be creative in general. However, you may not break up the matchsticks.

I've listed out the questions in the comments below. There is certainly more than 1 answer to each of these questions, so add your approach by replying to it. If you have similar questions, add them to this list too.

5) How do you make 5 squares from 4 matchsticks?

Uhhh

Make a square. Each matchstick is a "1", which is a square. The square is the last square.

The ends of the matchstick are a square. Place them together to form a larger \( 2 \times 2 \) square, giving you a total of 5.

Overlap 2 matchsticks on each side of an equilateral triangle. That is 2x2x2=8 triangles.

Create two attached tetrahedrons. That is 9 matchsticks, and contains 7 equilateral triangles.

Make an equilateral triangle with 3, and then overlap the remaining 6 all on the same side. There are 7x1x1=7 triangles.
