Good! I like the fact that u do your own research and come up wi

Theroy. This is my first time seeing it, I like to understand it a little more. I will call your theory "the same length theory" and it is basically SL1=SL2, BL1=BL2(big leg 2). The key is to choose the starting and the ending point. It seems that SL1and BL1 may share the same starting or ending point, and so do SL2 and BL2. But it is less convincing if SL1 and BL2 share the same starting point, like the orange color u drew. Don't u think so?
