Geometry Foundations: Mastering Triangles and Proofs

Triangles are the fundamental building blocks of geometry, yet many learners struggle to transition from memorizing formulas to writing rigorous proofs. This text-based course guides you step-by-step through the core principles of triangle geometry, equipping you with the logical reasoning and analytical skills needed for advanced mathematics and competitive exams. You will learn to approach geometric problems systematically, breaking down complex figures into solvable components. What you'll learn: Understand foundational definitions, classifications, and core angle properties of triangles; Master the principles of congruence and similarity using structured, logical proof techniques; Apply the Pythagorean theorem and basic trigonometric ratios to solve right-triangle problems; Learn to integrate coordinate geometry methods to analyze and prove geometric properties; Practice step-by-step problem-solving strategies designed for foundational and competitive mathematics. Starting with essential terminology and basic theorems, the course transitions into advanced congruence criteria, similarity proofs, and coordinate-based analysis through clear written explanations and structured practice exercises. This course is designed for beginners, high school students, and independent learners looking to build a strong mathematical foundation from scratch, with no prior advanced geometry knowledge required.
