Answer: Opposite and parallel sides of a parallelogram are equal.
Step-by-step explanation: First, a Parallelogram is a shape where the two opposite sides are parallel to each other and equal. For example in a Parallelogram KLMN, where line KN is opposite or say parallel to line LM, then /KN/ would be the same length as /LM/. In other words if the /KN/ is 5cm then /LM/ is also 5cm. Hence, if KN//LM then KN = LM
