In mathematics, plane geometry may refer to: •geometry of a plane, •geometry of the Euclidean plane, or sometimes: •geometry of a projective plane, most commonly the real projective plane but possibly the complex projective plane, Fano plane or others; •geometry of the hyperbolic...

Plane geometry is all about shapes like lines, circles and triangles ... shapes that can be drawn on a flat surface called a Plane (it is like on an endless piece of paper).

A line is one of the basic terms in geometry. ... Two lines in the same plane which never intersect are called parallel lines. We say that two line segments are parallel if the lines that they lie

then AB is parallel to CD. (For the definition of alternate angles, see Proposition I. 27 of Plane Geometry.)
