G-01 (1-1) Understanding Points, Lines, and Planes “I can identify and describe basic geometric terms and distinguish between line, line segments and rays”

Undefined Terms: you cannot measure them

Collinear: points on the same line Coplanar: points on the same plane Opposite of collinear is noncollinear and opposite of coplanar is noncoplanar. M K L N
