which of these quadrilateral types must have congruent diagonals. a. rectangle, square, rhombus b.square, rhombus c.rectangle, square d.parallelogram, rectangle, square, rhombus
( C. Rectangles and squares) This is because a square IS a rectangle and has alike properties. A rectangle always has congruent diagonals,therefore passing the property onto the square. Even though a square is a combination of a rhombus, a rhombus doesn’t have congruent diagonals. Finally, a parallelogram can be any shape so it doesn’t necessarily have to have congruent diagonals
