A rectangle is a quadrilateral in which all angles are right angles.
![[asy] size(200); pair A, B, C, D; A = (-377,233); B = (377,233); C = (377,-233); D = (-377,-233); dot("$A$",A,1.5*dir(A),linewidth(4)); dot("$B$",B,1.5*dir(B),linewidth(4)); dot("$C$",C,1.5*dir(C),linewidth(4)); dot("$D$",D,1.5*dir(D),linewidth(4)); draw(A--B--C--D--cycle); [/asy]](http://latex.artofproblemsolving.com/3/f/2/3f29ceb12d50d4780c9f4cd4300d7bfd7aa07314.png)
Every rectangle is a parallelogram and so has all the properties of a parallelogram. In addition, rectangles have congruent diagonals.
Squares are the only rectangles which are also rhombuses.
All rectangles are cyclic quadrilaterals.
