It's hard to create question names that make sense. Anyhow, the following is another question from my math assignment.
Line-segment AB has a fixed length of 10 units. point A moves on the positive x-axis and point B moves on the positive y-axis.
Point M is in the middle of line AB.
All right, I have been able to figure out the first question of the assignment: that M always stays on a circle from the Origin with a radius of 5.
However, the second question asks me to prove my answer from the first question.
How do I prove that M will always stay on this circle?
