The aim of this part is to help readers to practice their understanding in the first part. That means you must master your problem-solving skills. Remember that only a few people can solve all problems in this book. Always update books hourly, if not looking, search in the book search column.

Readers should keep in mind that learning maths is not about memorizing but it is all about understanding. In this part, we provide readers very detailed solutions to each problems. In the second part of the book, we listed many challenging problems from around the world.

endobj The Competitions are extremely interesting since many professors try to create new interesting problems. Point $E$ is on $AB$ with $AE = 10BE$, and point $D$ is outside triangle $ABC$ such that $DC = DB$ and $\angle CDA = \angle BDE$. Topics covered included cyclic quadrilaterals, power of a point, homothety, triangle centers; along the way the reader will meet such classical gems as the nine-point circle, the Simson line, the symmedian and the mixtilinear incircle, as well as the theorems of Euler, Ceva, Menelaus, and Pascal. 45 C. 15 D. 27 6.
