Titu Andreescu Geometry.pdf: A Collection of Geometric Problems and Solutions by a Renowned Mathematician
Titu Andreescu is a Romanian-American mathematician, educator, and author who has written many books on mathematics, especially on Olympiad-level problems. One of his books is Geometric Problems on Maxima and Minima, co-authored with Oleg Mushkarov and Luchezar Stoyanov, which was published by Birkhäuser in 2006[^1^]. This book contains hundreds of extreme-value problems, examples, and solutions primarily through Euclidean geometry. It covers topics such as Greek geometry and optics, Newtonian mechanics, isoperimetric problems, and recently solved problems such as Malfatti’s problem[^1^]. The book is intended for undergraduate students, teachers, and enthusiasts who want to learn more about geometry and optimization.

Another book by Titu Andreescu is Lemmas in Olympiad Geometry, co-authored with Sam Korsky and Cosmin Pohoata, which was published by XYZ Press in 2016[^3^]. This book showcases the synthetic problem-solving methods which frequently appear in modern day Olympiad geometry, such as angle chasing, cyclic quadrilaterals, power of a point, homothety, inversion, transformations, collinearity and concurrence, etc. It also introduces some advanced topics such as projective geometry, mass points, spiral similarity, etc. The book contains over 300 problems and solutions from various national and international mathematical competitions[^3^]. The book is aimed at students who are preparing for mathematical Olympiads or who want to improve their geometric skills.

Both books are available in PDF format online for free download from the Internet Archive[^1^] [^2^]. They are valuable resources for anyone who loves geometry and wants to challenge themselves with some interesting and elegant problems.


Titu Andreescu has a remarkable biography as a mathematician and educator. He was born in 1956 in Timișoara, Romania, where he developed a passion for mathematics from an early age. He won the Romanian national problem solving contests organized by Gazeta Matematică three times in a row from 1973 to 1975. He graduated with a B.S. and M.S. degree from the University of Timișoara and became a professor of mathematics at the Constantin Diaconovici Loga school of Mathematics and Physics. He also served as the editor-in-chief of the Periodical Revista mathematică din Timișoara and as a coach for the Romanian International Mathematical Olympiad (IMO) team. In 1984, he was appointed as "Counselor of the Romanian Ministry of Education".[^2^] [^4^]

In 1990, after the fall of communism in Eastern Europe, Andreescu emigrated to the United States, where he taught at the Illinois Mathematics and Science Academy. He earned his Ph.D. degree from the University of Timișoara in 2003. He is currently an associate professor of mathematics at the University of Texas at Dallas. He is also deeply involved in mathematics contests and olympiads at various levels, having been the Director of American Mathematics Competitions (as appointed by the Mathematical Association of America), Director of the Mathematical Olympiad Program, Head Coach of the United States International Mathematical Olympiad Team, and Chairman of the United States of America Mathematical Olympiad. He has received many awards and honors for his contributions to mathematics education and problem solving, such as a Certificate of Appreciation from the Mathematical Association of America for "outstanding service" as coach of the United States Mathematical Olympiad Program.[^2^] [^3^]

Titu Andreescu is also a prolific author who has written or co-written more than 40 books on mathematics, especially on Olympiad-style problems. Some of his books are Mathematical Olympiad Challenges, Mathematical Olympiad Treasures, Mathematical Reflections: In a Room with Many Mirrors, Number Theory: Structures, Examples, and Problems, Complex Numbers from A to Z, Mathematical Induction: A Powerful and Elegant Method of Proof, etc. He is also the founder and director of AwesomeMath, which includes a summer program for students training to succeed at the Olympiad level, a correspondence-based lecture series for students continuing education, called AwesomeMath Year-round, and Mathematical Reflections, a free online journal focused primarily on mathematical problem solving.[^3^]
