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.
Triangles do not necessarily have right angles, but they can. A triangle with a right angle is called a right triangle. A triangle cannot have more than one right angle, since the total of all three angles of every triangle equals 180°.
Not possible... The internal angles of a quadrilateral always total 360. If you MUST have an angle of 90 degrees - the remaining angles must total 270. At least one of the remaining angles will always be obtuse.
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.
No. A parallelogram only has a total of 4 angles. They may either all be right angles, or none of them is a right angle.No. A parallelogram only has a total of 4 angles.

A right angle has a 90-degree and in two acute angles.
A scalene or any other kind of triangle can have no more than one right angle, because a right angle = 90 degrees, a triangle must have total interior angles of 180 degrees and must have three angles. If there were two right angles, the third angle would have to be zero degrees, and the supposed triangle would be a straight line.
Acute triangles. They can have three angles, all less than 90 degrees (total is 180 degrees).Shapes with more than three sides must have angles of 90 degrees or more because the total of their angles must be 360 degrees (quadrilaterals) or more.
Since a triangle has 3 angles that total 180 degrees, it can have only 1 right angle. Since a triangle has 180 degrees and 3 angles, it can only have 1 right angle.
Any two angles that total 90 degrees will make up a right angle. Two 45 degree angles will make a right angle - 90 degrees. Also an angle of 30 degrees and another angle of 60 degrees will make up a right angle.
A single right-angle has an angle of 90 degrees, whichever way up it is. Therefore TWO right angles would have a total of 180 degrees.
They total 90o
