The MN = LK because MN and LK are equal and parallel since it's a square, and squares have four equal sides.
What is parallelogram?
In two-dimensional geometry, it is a plane shape having four sides, in which two pairs of sides are parallel to each other and equal in length. The sum of all angles in a parallelogram is 360°.
We have given:
KLMN is a parallelogram.
As we know from the definition of the parallelogram the two sets of opposite sides of a parallel and equal.
MN and LK are a pair of the opposite side
∴ MN = LK
MN = LK because there both parallel.
Thus, the MN = LK because MN and LK are equal and parallel since it's a square, and squares have four equal sides, or MN and LK are a pair of the opposite side.
