Three - in an arrowhead, for example.
It is just an irregular quadrilateral.
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.

A kite can satisfy those criteria.
A quadrilateral with one acute angle and one obtuse angle can be a trapezoid or an irregular quadrilateral. In this case, the acute angle measures less than 90 degrees, while the obtuse angle measures more than 90 degrees. The other two angles can be either acute or obtuse, but they must sum with the given angles to equal 360 degrees. This flexibility allows for various shapes while still meeting the criteria.

A quadrilateral may have zero, one, two, or three acute angles.
A quadrilateral with one acute angle and one obtuse angle can be a trapezoid or an irregular quadrilateral. In this case, the acute angle measures less than 90 degrees, while the obtuse angle measures more than 90 degrees. The other two angles can be either acute or obtuse, but they must sum with the given angles to equal 360 degrees. This flexibility allows for various shapes while still meeting the criteria.
A quadrilateral can have three acute angles if it is an irregular shape, specifically a type of concave quadrilateral. In such a case, the fourth angle can be obtuse or even reflex, allowing the sum of the angles to equal 360 degrees while still accommodating three acute angles. However, it's important to note that a convex quadrilateral cannot have three acute angles, as the fourth angle would then have to be obtuse to satisfy the angle sum property.
No, It is not possible to have a quadrilatera with four acute angles because the addition of four angles for quadrilateral = 360 & acute angle is less than 90 degree
