Question

Prove that a rectangle has congruent diagonals. Be sure to create and name the appropriate geometric figures.

Answer 1

Pythagorean theorem comes to mind.

Answer 2

Why is that? I'm really bad at proofs

Answer 3

I don't know anything about formal proofs, but if \(a^2+b^2=c^2\) the \(c\) will be the diagonal of the rectangle. Let me try to draw a picture...

Answer 4

I understand that part

Answer 5

So if both equations are the same, then the diagonals must be congruent, right?

Answer 6

Right

Answer 7

Like I said, I'm not familiar with formal proofs. I would just show work for each equation with a diagram labeling all sides.
