Hi everyone,
I'm trying to teach myself math when I'm not at work and don't have access to a tutor. I'm currently working on Geo/Trig.
In my textbook, questions 1-8 are straight forward and simple variations of each other, finding the distance between coordinates on a graph. The last question of the list is very different.
The question: "Find x so that points A (x, x + 1), B (x + 2, x + 3) and C (x + 3, 2x + 4) form a right-angled triangle.
The answer in the textbook is: "x = -2 or -6"
Knowing the answer hasn't been able to help me determine where to even start on this.
An initial thought of where to begin was to determine which of the two points form the hypotenuse - which I think would be AC. Even if AC is the hypotenuse, I'm unsure how to proceed.
If someone would like to explain the process of understanding this, it would be much appreciated. Thank you.
