I used to get really mindfucked by tangents. How can a line intersect with a point on a circle to form a ninety degree angle with the line only touching one point? A circle is made of an infinite number of points. Points have no width or height. How can a line hit only one exact point on the circle without brushing into an infinite number of points right next to it that make up its curve?
