Square PQRS has vertices P (2, 6), Q (6, 5), R (5, 1).  What are the coordinates of S?

There are three ways to do this.

 

Method 1: Use a graph

Using Desmos, I potted these points down: https://www.desmos.com/calculator/zysdy00pui

We see that S = (1 , 2)

 

Method 2: Geometric intuition 

Nothing to explain, you just need a lot of memory space in your brain to solve all those line adding things. (Which I don't have)

 

Method 3: Ask the internet

I see you've done that already.

 

i personally enjoy method 1
