Find the midpoint of each diagonal of a square with side of length s. Draw the conclusion that the diagonals of the square intersect at their midpoints.
HINT GIVEN IN BOOK: Use (0,0), (0,s), (s,0) and (s,s) as the vertices of the square.
so diagonals are AC and BD
using midpoint formula
midpoint of AC=(S/2,S/2)
midpoint of BD=(S/2,S/2)
SINCE they have same mid point they also intersect at the midpoint
