This book is a structured and engaging guide for students beginning their journey into geometry. It uses visual examples and simple language to explore foundational geometric concepts, offering both theoretical explanations and practical exercises to build a solid mathematical understanding.

In this book we are going to study the basic concepts and principles of angles and triangles in Euclidean plane
geometry. Today we can describe geometry as the branch of mathematics which is concerned with the properties of
shapes and figures in the plane and in space, although the study of geometry is a very old practice that began
thousands of years ago.

This book is all about the science of how chemical phenomenons actually happen and what affects their speed. Instead of just giving overview, it digs into the hidden details of why some phenomenons are so complex and why some are so simple. It also explores how scientists figure out the exact steps in which atoms rearrange, how they simplify really complicated phenomenons into workable models, and why different factors like temperature and pressure play such a big role in chemical phenomenons. In simple words, it’s like a guide that helps you peek behind the curtain to see what chemical phenomenons really do and how exactly they work.
