For mastering Euclidean geometry at the elementary and pre-college levels, several key texts are recommended. "Advanced Euclidean Geometry" by Roger A. Johnson is noted as a solid resource, but "Elements" by Euclid is considered essential for foundational understanding. Kiselev's Geometry is suggested for beginners seeking a straightforward introduction. Additionally, "Geometry Revisited" and "Introduction to Geometry" by H.S.M. Coxeter are highlighted for their depth and comprehensive coverage, with the latter being particularly detailed. Edwin Moise's work is also mentioned as a valuable resource for learners. Overall, these texts collectively provide a robust framework for studying Euclidean geometry.
