Math Problem #9

I got one reply in the last one. It was the right answer, but they didn't justify it, so I'm not assigning credit to anyone for solving.

Here are some more puzzles regarding pentominoes, which on a grid, are 5 blocks which are all adjacent.

For example a 5x1 rectangle is a pentominoes, because it consists of 5 adjacent 1x1 blocks. Likewise is a 2x2 square with 1 adjacent 1x1 square to one side.

The objective is to take a grid with triangles, and be able to construct pentominoes which support them (that would keep them from falling downwards).

However, a pentomino must be supported by another, or it will fall as well. And a pentomino cannot be supported by a triangle (must eventually reach flat ground). We're not considering unbalanced weights. As long as the pentominos are supported by pentominos which eventually reach the bottom, it is okay.

Here is an example of a puzzle:

And a corresponding solution:

Here are puzzles for you to work on:

Sorry, I forgot to add. You only have 12 of these pentominoes that you can use, however the shapes of these pentominoes can be anything as long as they are still pentominoes.

Re: Math Problem #9

Can no one solve these puzzles? Is the challenge too great for you? Does the disburbing notion of thinking cause you to roll over in bed and give you restless sleep?

I CHALLENGE you! Solve some or even all of these puzzles to receive the honor of being a netaliver not afraid of a little thinking.
