There are no acute angles in a rectangle which has 4 equal interior right angles
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)
An acute angle is less than 90 degrees. Therefore, as a rectangle has 4 right-angles (90 degrees) there are no acute angles.
There can be 4 different acute angles in an irregular 4 sided quadrilateral that all add up to 360 degrees.

Two (or none, if it is a rectangle).
cxcvcdv
A quadrilateral may have zero, one, two, or three acute angles.
A parallelogram has 0 or 2 acute angles. If the parallelogram happens to have four right-angled corners, it is still a parallelogram (and a rectangle), but no acute angles.
None. They are all right angles.
None because a rectangle has 4 interior right angles
A rectangle is a 4 sided quadrilateral that has 4 vertices and 4 interior right angles.
