drawing lines an exact angles

Community matplotlib-users

Hello:

I am trying to create a drawing for slope stability analysis and I need to draw lines at certain angles with certain lengths and than to calculate the angle of the lines intersections. Is it possible to use matplotlib?

Thank you in advance

Matplotlib can plot the lines, but there’s not anything inherent to the calculation of the angle of intersection. But if you represent the slopes as vectors, the angle of intersection can be found from the dot product of the vectors.
