Adjoint curves obtained from some special curves and their characterizations

This study consists of four parts. In the introduction section, the history of the subject, its areas of use and studies on them are mentioned. The general information section includes definitions, theorems and proofs on the subject. In the material and methods section, the important points of the thesis, namely the curves used, definitions, theorems and frames regarding the modified frame and adjoint curve were given. The main idea of our thesis is in the findings section. Here, Involute-Evolute, Bertrand curve pair and Mannheim curve pair were first modified. Then, adjoint curves obtained from these curves were found. Finally, the obtained adjoint curves were modified and their connections with the main curve were calculated.
