Geometry - Dealing with Tangents


Considering a two dimensional figure, a tangent is a line that touches a curve at a single point. In each of these cases, the line touches the curve at a single point. In the case of a circle, when yo...

Geometry - Maximum Distance between Points in 3D Objects


How do we find the the two farthest points on a 3D object? For example, we know that on a circle, any two points that are diametrically opposite will be the farthest from each other than from any othe...
