Which statement explains how you could use coordinate geometry to prove the diagonals of a quadrilateral are perpendicular? Use the slope formula to prove the slopes of the diagonals are the same.
Use the slope formula to prove the slopes of the diagonals are opposite reciprocals.
Use the distance formula to prove the lengths of the diagonals are the same.
Use the distance formula to prove the midpoints of the diagonals are the same.

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
