9-1 Introduction to Geometry: Points, Lines, and Planes – We learned the basic geometric figures. Next we learned that a point has no dimensions. A line is one-dimensional having no width or height. You cannot measure the end of a line because it has no end. A plane has two dimensions length and width but no height. You cannot measure length or width of a plane because it extends forever. The simplest figure you can measure is a line segment. Then we learned to recognize intersecting lines, parallel lines, and skew lines.
