In our last lesson, we learned about some of the building blocks of geometry. Today, we are going to continue learning about lines, but first let's review what we have already learned in our last lesson.
In our last lesson, we learned to define and identify some of the basic terms of geometry. Let's start by talking about lines.
A line is a series of connected points that extends in both directions without any definite endpoints. A point is a defined location. A point can be on a line or on a plane or in space. We see points and lines in all kinds of geometric shapes and figures in real life each and every day.
When there are several points on a line, we say that the points are collinear. Let's look at a diagram to continue our review.
