I have a question from my textbook:
Given Square PINK with vertices P (-1,-1), I (3, 2), N (6, -2) and K (2, -5) prove that its diagonals are congruent and are perpendicular bisectors of each other.
I'm really not sure what I am supposed to do once I have this sketched up.
Hello, (?)G!
Given Square PINK with vertices P (-1,-1), I (3, 2), N (6, -2) and K (2, -5)
Prove that its diagonals are congruent and are perpendicular bisectors of each other.
I'm really not sure what I am supposed to do once I have this sketched up.
How about doing the part in blue?
Determine the lengths of diagonals and , and show that they are equal.
Find the slopes of and and show they are perpendicular.
Find the intersection of and and show that it is their mutual midpoint.
