WebbCeva Theorem Proof Calculator. The Ceva Theorem states that in a given triangle ABC, in which the points F,E, and G lie on lines CB, BA, and AC respectively, the lines AF, CE and … WebbTheorem , this implies P, Q R are collinear. We remark that there are limiting cases of Pascal’s Theorem. For example, we may move A to approach B. In the limit, A and B will coincide and the line AB will become the tangent line at B. Below we will give some examples of using Pascal’s Theorem in geometry problems.
