Answer: If two quadrilaterals are congruent, then there must be four pairs of corresponding sides.
Explanation:
We know that if two polygons are congruent then their corresponding sides and angles are congruent .
Such that for any two polygons having 'n' sides are congruent, then there must be 'n' pairs of corresponding sides.
- A quadrilateral is a polygon having four sides.
Therefore, if two quadrilaterals are congruent, then there must be four pairs of corresponding sides.
