90 degrees because it's a right angle, they're always 90 degrees
a quadrilateral can have from 0 to 4 right angles. But it can't have exactly three right angles. The interior angles of a quadrilateral sum to 360 degrees. If it had three right angles and x were the measure of the fourth angle: 3*90+x=360 x=360-270=90 So if it has three right angles, the fourth angle would be a right angle as well.
a square or a rectangle
It could be a kite, an arrowhead or an irregular quadrilateral with a right angle - which has no specific name.
A quadrilateral with all right angles is a rectangle.
A square or a rectangle
A regular quadrilateral is a square and each angle is 90 degrees (i.e. a right angle).
-- Rhombus -- Regular parallelogram
a quadrilateral with no right angle is?
yes, you can draw a quadrilateral with on right angle because all sides don't have to be equal for a regular one _ /Right Angle l l l l l/ --------------------------------------------------------------------------- A quadrilateral is a polygon with four sides, so yes. You can use only one right angles, if the polygon has four sides.
A rectangle is a quadrilateral (four sided shape) with four right angles. Therefore, the measure of every angle is 90 deg.
A quadrilateral can have four right angles.

All polygons can have right angles except for circle and ovulated shapes. The only 'regular polygon' that has a right angle is the quadrilateral.
No a quadrilateral can't have 3 obtuse angles and 1 right angle because if a polygon did have 3 obtuse angles and 1 right angle then it would not even be a quadrilateral.
a square or a rectangle
A rectangle or a square.
That is called a rectangle.
