An acute angle is less than 90 degrees. Therefore, as a rectangle has 4 right-angles (90 degrees) there are no acute angles.

A rectangle has four right angles, while a regular pentagon has none. Therefore, a rectangle has more right angles than a regular pentagon.

It has none because a rectangle has 4 equal interior angles of 90 degrees

If ONLY two right angles, then it could be a right angled trapezium or a kite If more than two it must be a rectangle (a square is an equilateral rectangle).

There are fewer obtuse angles than the other two kinds. There are the same number of acute and right angles and so the sum of the measures of the acute angles will be less than 5 right angles. The sum of two obtuse angles will be less than 5 right angles but may be less than, equal to, or more than 5 acute angles.

Yes. The reason why is because a rectangle is a quadrilateral with four right angles and a rhombus can have four right angles and it is also a quadrilateral.

First of all the plural of 'Rhombus' is 'Rhombi'. Rhombi do NOT have 90 degree angles , so they are NOT RECTANGLES. However, they are QUADRILATERALS.
