Nico and karina wrote these statements in their math journals nico- a 4-sided polygon with at least one pair of parallel sides must be a parallelogram. karina- a 4-sided polygon with at least one pair of parallel sides must be a trapezoid which describes the accuracy of their statements and why? nico is correct because if one pair of sides in a quadrilateral is parallel, the other pair must be also. karina is correct because a trapezoid has exactly one pair of parallel sides. both are correct because a 4-sided polygon with at least one pair of parallel sides must be both a parallelogram and a trapezoid. neither is correct because a 4-sided polygon with at least one pair of parallel sides could be either a parallelogram or a trapezoid. hurry 20
