Section 3-6: Perpendiculars and Distance

In this section we learned how to find the distance between a point and a line. Here is the picture for it:

We also learned a new term, equidistant. 2 things are equidistant if they are the same distance from a given object. An easy way to remember this is the two words that make up the word equidistant. "Equal" and "distant/distance". That way, you can know that it means two things that have an equal distance.
We learned a new theorems too. Here it is:
