Coplanar lines are lines lying in the same plane. This keyboard contains multiple coplanar parallel lines (in red). The lines in between the keys are straight, will never intersect, and are in the same plane. The keyboard was found on my laptop, and is used everyday by many because it is what helps you type on a laptop. Keyboards can be used by authors, students, teachers, etc. A keyboard falls under the category of information technology because many researchers use the technology of laptops and find data. I took this photo on my camera.
