{wiki=Category:Theorems_in_plane_geometry}
Theorems in plane geometry are propositions or statements that can be proven based on axioms, definitions, and previously established theorems. Plane geometry deals with flat, two-dimensional surfaces and includes the study of points, lines, angles, shapes (such as triangles, quadrilaterals, and circles), and their properties.
