No, because the sum of all the angles is always 360 degrees. If 3 of the angles are acute (less than 90), then the sum of these must be less than 270. Therefore the remaining angle must be obtuse (greater than 90), so that the sum of all 4 is 360.

A quadrilateral can have 0 to 3 acute angles, but never 4:A rectangle and a square are both quadrilaterals with four right angles, hence they have no acute angles.A kite-shaped figure can have one acute and three obtuse angles, or three acute and one obtuse angles.A parallelogram and a rhombus have two acute and two obtuse angles.The sum of the interior angles of any quadrilateral is 360º; thus it would be impossible for all angles to be acute (less than 90º each)
Quadrilaterals have 4 sides, 4 angles, and 4 vertices.
ALL quadrilaterals have 4 angles
A rectangle has four right angles. Otherwise it wouldn't be a rectangle.
no it has 4 right angles
