Let's use the distance formula to find the distance between the origin and each of the points. We can use this to show that the distances are the same. Remember that the distance formula is:

is one point
is the other point that you are trying the distance to
First, let's find the distance between the points (3, 1) and the origin, (0, 0). We will call this distance
.



Next, let's find the distance between (1, 3) and the origin, (0, 0). We will call this
.



We can see that
, or that the distances are the same. ✔︎
