J. Lester gave two different proofs for this theorem in Euclidean plane [1] and Euclidean space [2]. In this study a new technique is developed for the proof of this theorem which is valid in both Euclidean plane and Euclidean space.</p>}, number={2}, journal={Mathematical Journal of Interdisciplinary Sciences}, author={Demirel, Oğuzhan and Aslan, Leyla and TOPAL, Damla}, year={2020}, month={Mar.}, pages={57-59} }
