Distance and circles are all just pythagorean theorem!

September 20, 2019

Today we looked at the distance between 2 points. We had an easy time if the segments were horizontal or vertical, but stumbled when we had to calculate the distance of a segment that is diagonal. Pythagorean theorem helped us out!

We also looked at the group of points that are a fixed distance from the origin (0,0). This example is a lot of points that are 5 units from the origin. It makes a circle!

We now know the equation of a circle is x^2+y^2=r^2.
