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. Example 1 (2001 … Webb21 jan. 2024 · Ceva's theorem states that, given a triangle ABC, and a point O not incident with any of the lines determined by the sides of the triangle, such that the lines AO, BO and CO meet the lines BC, CA and AB, respectively, in the points D, E and F. Then, again with oriented ratios AF FB ⋅ BD DC ⋅ CE EA = 1.

What is Ceva

WebbThe point of Ceva's theorem is that it provides a relatively simple calculation (using ratios) you can do that will tell you whether or not the three cevians really do concur. The theorem actually works in two directions: if the calculation holds then the segments concur, and if the segments concur then the calculation holds.
