Collinear Points


Use the line tool to draw a line between any two points, then reset the view or undo the line command with the controls in the upper right corner. Use the line tool and select a different pair of points. Repeat as many times as you like.


We can name a line by two points that it passes through. How many different ways can you think of to name the line created in this exercise? Remember that different names mean different pairs of points. For example, Line AB and Line BA would be the same name.
