This could be a silly question but I did not understand it very well.

I did not understand how [(x_D_x - x_C_x) (y_D_x - y_C_x)] becomes [A B].

That's because I defined A and B as (x_D_x - x_C_x) and (y_D_x - y_C_x) respectively at the beginning of the equation derivation. image

Ohh, somehow I completely missed it. Thanks for the clarification! :+1:
