In this lesson our instructor talks about points lines and planes. She defines and show examples of points, lines and planes. She talks about drawing and labeling. She does four example problems. Four complete extra example videos round up this lesson.
A line passes through two points. Lines consist of an infinite number of points. A line is often named by two points on the line or by a lowercase script letter.
A plane is a flat surface that extends indefinitely in all directions. Planes are modeled by four-sided figures. A plane can be named by a capital script letter or by three non-collinear points in the plane
