Ответ:
Use the distance formula six times to show that the opposite sides and the diagonals are congruent
Step-by-step explanation:
A polygon is a two-dimensional shape formed using straight lines. A rectangle is a four-sided polygon in which all the interior angles are right angles.
Also, the opposite sides of the rectangle are parallel and of equal length.
Both diagonals of a rectangle are also congruent.
A rectangle is a quadrilateral in which opposite sides and the diagonals are congruent.
