I hear people talking about black,red and green triagles,I know what greens are but what about blacks and reds?

A green triangle is the basic triangle you get from the trianlge slack. A black triangle is also called a cross arm triangle, which is pretty self-explanatory. A red triangle is also called a fake green triangle. You won’t get knots if you drop red triangles.

Addment. That’s the short version

Red triangles are fake gts. They are easy to get into. Just get a trapeze, put ur finger into the hole of the trapeze, and pull the string out. Thats ur red gt!

well in that case I know them all,thanks!

black gt is awsome:
