Coordinate geometry studies geometric figures using algebraic equations on a plane. It covers points, lines, slopes, distances, midpoints, circles, and conic sections, linking visual shapes with coordinate formulas. This category provides explanations and practice questions to build a solid foundation.
Think of it like this: complete solution: write formula, plug data, do arithmetic. Final value matches 30°. Simple and accurate.
