To answer this question,
# You need to know the total number of degrees possible for the angles of a quadrilateral to add up to. # You need to know how many degrees in a right angle. # You need to be able to multiply that answer by 3 and subtract the total from the answer to number 1.

you can draw or imagine a 4-sided figure with three right angles and note the position of the lines that form that fourth angle. There is only one choice. What must that angle be?
A quadrilateral can have two right angles and still not be a rectangle, if one side is oblique (neither right nor parallel) to the others, but three right angles force the fourth, and you have a rectangle.
A quadrilateral can have four right 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.
It is just an irregular quadrilateral.
No quadrilateral with 2 internal right angles can be anything other than a square or rectangle. The shape described in the question does not exist.Improved Answer:-It could be a trapezoid with two right angles, an acute angle and an obtuse angle.
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.
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 quadrilateral with no right angle is?
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.
if a quadrilateral has three right angles will also have have a fourth right angle. Making it a rectangle. The addition of all the angles in a triangle is 360 degrees. If there are three right angles, and you subtract their addition by 360, you will get ninty degrees.
A quadrilateral can have two right angles and still not be a rectangle, if one side is oblique (neither right nor parallel) to the others, but three right angles force the fourth, and you have a rectangle.
A quadrilateral can have four right angles.
The only quadrilaterals that always have all four right angles are the square and the rectangle. All four angles in a quadrilateral must add up to 360 degrees.It is possible to have non-regular quadrilaterals with one or two right angles. A quadrilateral with three right angles becomes either a square or a rectangle, because its fourth angle must also be a right angle.
Quadrilaterals are polygons having four sides. Quadrilaterals may have 1, 2, or 4 right angles. It is impossible for a quadrilateral to have exactly 3 right angles because the fourth angle would also be a right angle.
A trapezoid can't have three right angles. A quadrilateral with three right angles must have a total of four right angles, since a quadrilateral's interior angles add up to 360. 360 - (3*90) = 90, so the fourth angle would have to be right as well. A quadrilateral with four right angles is not a trapezoid; instead it is a rectangle or a square.
The sum of the interior angles of a quadrilateral is 360 degrees so if 3 of them are right angles (90 °) the remaining fourth angle must also be 90 °. 360° - 3x90° = 90°
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.
