Plot points in 3D and then show lines connecting the points?

My objective is graph 3 points in 3D and then connect the points with straight line segments to help students visualize the triangle created. I was able to plot the 3 points by entering 3 points in [Table1], but I could not figure out if there was a way to show the line segments connecting the points.

Any advice?

Hi Jim,
In order to see lines or surface of a triangle you need at least 4 points. The 4 points will generate a rectangle shape so in order to make it triangle simply duplicate the 3rd point.
