Not quite congruent. One partner has landed while the
other is still up in the air.
This is only the third day and we have a couple more to go. Things do get more interesting and more challenging when we start combining individual patterns into larger ones (i.e. start the second pattern where you ended the first, not at your original starting point and then try the reverse) and also when we transform the patterns using turn symmetry which seems rather straightforward in a static representation on paper, but is absolutely spectacular when you see it in motion.
I'll keep you posted!
