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
