What is Geometry?
Geometry is the branch of mathematics studying size, shape, position, angles, and dimensions of objects.
It governs architecture, surveying, manufacturing tolerances, and physics.
Formula & Step-by-Step Calculation
A = l × w, V = l × w × h, C = 2πr
Standard Euclidean geometric formulas for dimensions and space.
