Answer 12

well going off what we said earlier

you can use the letters from left to right or right to left

so <ABC and <CBA for a start

you can also use the point that is directly on the angle (point B) so <B
you can also use the number inside the angle so <1

Answer 13

<ABC
<CBA
<B
<1

is that correct ?

Answer 14

yes
