The goal is to make of these four pieces a symmetric capital T. You're
allowed to rotate the pieces as you wish and even turn them over, but
they must not overlap each other in the final letter.
In fact there are two symmetric capital T letters that you can get
from these pieces. Try to find both of them.
By the way, there is at least one more extra symmetric shape that can
be formed from this set - isosceles trapezoid. Can you find it too?
