This is especially important in geometry questions because it can help you visualize specific theorems, identities, propreties, et cetera.
(Yes, the circle was not well-cropped 😐 )
But if you don’t draw the line accurately enough, the two shapes won’t be tangent. You will know they are tangent, in the moment. Once you spend some time looking at other constraints in the problem, you might forget that they were tangent, and thus be unable to solve the question quickly.
