A rectangle has 2 pairs of parallel sides and its diagonals are of equal length but do not cross each other at 90 degrees
rectangle
No.
The cross section of cylinder along its length (parallel to the axis of symmetry has the shape of a rectangle.
The diagonals of a rectangle do not cross at right angles
The diagonals of a square and a rhombus cross at right angles.
It depends on the inclination of the line of cross section. If it is at an incline to the sides and diagonal, the cross section is a point which becomes a line that increases in length, reaches a maximum, remains at that length and then shrinks back to a point. If it is parallel to a diagonal, the cross section is a point which becomes a line that increases in length, reaches a maximum and then shrinks back to a point. If it is parallel to a side, the cross section is a line of constant length.
A parallelogram (or rectangle) which is not a rhombus (or square).
A rectangle would fit the given description
A rectangle.
No.
Because it has 4 sides of equal lengths and its diagonals cross at 90 degrees. It looks like a tilted square with opposite parallel sides
The diagonals do not intersect (cross) at 90 degrees.
yes, they do. though they are not always equal in length they always cross at right angles.
A parallelogram
The cross section of cylinder along its length (parallel to the axis of symmetry has the shape of a rectangle.
Yes and they are perpendicular to each other thus forming right angles of 90 degrees
A rhombus has unequal diagonals which intersect at right-angles.
A kite
