No a quadrilateral does not have any rightangles.
Usually none but it's quite possible for it to have two.
Sum of interior angles = (2n -4) rightangles So we have 2x14 - 4 = 24 right angles = 6 x 360 = 2160 degrees
720 degrees * * * * * The internal angles of any quadrilateral add to 360 degrees.
There are 3 different types: ordinary, isosceles and right which has 2 right angles
