No. An acute angle is a angle less than 90 degrees. A recatangle doesn't have any of those. It has only right angles (90 degrees).
A rectangle has four sides.
Yes, always. But a parallelogram is not always a rectangle.
Each angle of a rectangle is a right angle. (90°)
Each interior angle is 140 degrees. Each exterior angle is 220 degrees.
Each exterior angle: 45 degrees Each interior angle: 135 degrees
Each exterior angle: 60 degrees Each interior angle: 120 degrees
It is a square or a rectangle where each interior angle is a right angle of 90 degrees.
Each exterior angle: 40 degrees Each interior angle: 140 degrees
Providing that it is a regular nonagon then each exterior angle measures 40 degrees and each interior angle measures 140 degrees
a right angle
Each angle in a square is 90 therefore each angle is a right angle.
