Fully solved YKS-TYT-AYT **Geometry Lecture Notes** (Charcoal Solutions). This page contains questions and solutions about geometry.

In these notes; It contains information that allows you to look at the classic or new generation questions with a clear and plain expression without confusion and to interpret them correctly.

With these written special lecture notes, those who want to increase their knowledge of geometry and consequently their success in the course can make a contribution to them. Although we have this idea, our studies are constantly continuing to ensure that the geometry course is competent in terms of data.
