Transformations on a Pegboard

Lucy, who is educated at home, sent in a very clear solution to this question. For the first part she wrote:

You move the top peg to the right by one space. If you cut a square from all four corners, you end up with a quarter of it. In the middle of the square you get four right angles.

I think there is at least one other way to get a right-angled triangle. Can you see how?

Lucy continued:

For the second problem you know that the new shape is going to have sides 4x8 because the sides are multiplied by 2. One of the sides is already 4 so you just move the two right pegs 6 spaces to the right.

Very well described solutions Lucy, thank you.
