'B' and 'D'. The diagonals are equal to each other in rectangles and squares.
No. A small pentagon will have smaller diagonals than a large pentagon! However, all the diagonals of a regular pentagon will be congruent.
All quadrilaterals (four sided shapes) have 2 diagonals.
The quadrilaterals with all angles congruent are rectangles and squares. They are the only quadrilaterals in which all four angles are right angles.
All but the square and rectangle.
