Quick overview of a perpendicular line.

Perpendicular
Welcome to MooMooMath. Today we are going to look at
perpendicular lines. What are perpendicular lines or what is perpendicular?
Well perpendicular are two lines that intersect at 90 degree angles. So let’s
look at a couple of examples of where we will see those. So we have two lines
and they are intersecting at 90 degree angles, and I will label it with a
little box that represents 90 degrees, and once we know this is 90 degrees we
know the other three are 90 degrees because these are lines and lines have a
degree of 180 so that would make all four of these 90 degrees. Now let’s look
at the two line segments. This angle is 90 degrees and you will often see this
in a right triangle. So a right triangle has two segments that are perpendicular
and measure 90 degrees. So that is perpendicular lines. Hope this helps
