A rectangle.
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 not possible for a quadrilateral in Euclidean plane geometry to have no equal angles and still have its opposite sides parallel.It's possible for a quadrilateral to have no equal angles and two of its sides parallel (opposite ones, obviously; adjacent sides can't possibly be parallel). That would be a trapezoid.
Oh, dude, you're talking about a square, man. It's the shape that's like, "Yeah, I got four sides, but three of my angles are all chill and equal, you know?" So, next time you see a shape with those equal angles, just give it a little nod and be like, "Sup, square."
If you mean all right angles are equal in MEASURE, then this would be a square or a rectangle, but if you meant 4 right angles and 4 sides of equal length then that would be a square.
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 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.
It has 2 opposite equal obtuse angles and 2 opposite equal acute angles whereas a square has 4 equal angles of 90 degrees
A square or maybe a rectangle as well would fit the given description
The sum of all the interior angles of a quadrilateral is 360 degrees. If it had more than three obtuse angles, then it would have all four angles greater than 90 degrees so that their sum would be greater than 360 degrees.
Equiangular means "having equal angles" or "with all angles equal" or the like. An equilateral triangle (a triangle having all 3 sides the same length) is equiangular. Each of it's interior angles is 60 degrees. A quadrilateral (a 4-sided figure) that is equiangular would have to have each of its interior angles equal to 90 degrees, and the quadrilateral would then have to be a rectangle.
A rhombus would fit the given description.
A square would fit the given description.
