4 angles
No, a quadrilateral can't have three acute angles and one right angle. The angles of a quadrilateral must total 360. The three other angles of a quadrilateral with one right angle would then have to total 270 degrees. If all three were acute (less than 90 degrees), they could not total 270.
Interior angles of any quadrilateral always total 360o.
In a quadrilateral the sum of all four angles equals 360º.
