Prove: The diagonals of a square are perpendicular.

Prove The Diagonals Of A Square Are Perpendicular class=

Answer :

Answer:

Step-by-step explanation:

Slope of AC= (a-0)/(a-0) = 1

Slope of BD = (0-a)/(a-0) = (-a)/a =-1

Slope of AC x Slope of BD =1 x -1 = -1

Therefore AC perpendicular to BD
