A rectangle or a square.
A square or a rectangle
The sum of the interior angles of a quadrilateral is 360 degrees. If three of the angles are right angles, that is, of 90 degrees each, the the fourth must be 90 degrees. So you can have a quadrilateral with three right angles but its fourth angle will also be a right angle. So exactly 3 right angles is not possible.
It could be a kite, a trapezium, a chevron or just an irregular quadrilateral with one right angle and no specific name.
It is a parallelogramIf one of the angles is a right angle (then they all are) and the quadrilateral is a rectangle.If both pairs of sides are equal in length (but none of the angles is a right angle) the quadrilateral is a rhombus.If the sides are equal and one of the angles is a right angle, the quadrilateral is a square.
yes
It is a square or a rectangle where each interior angle is a right angle of 90 degrees.

A quadrilateral with all right angles is a rectangle.

A rectangle, or could be a square if lengths are the same.
Either a square or a rectangle
a quadrilateral with no right angle is?
A regular quadrilateral is a square and each angle is 90 degrees (i.e. a right angle).
