1 revolution = 360o
1 right angle = 90o
Thus 360o ÷ 90o = 4 right angles in one revolution.
In one complete revolution, there are four right angles (90 degrees each), corresponding to the four quadrants in a circle. Therefore, in two revolutions, there are a total of eight right angles.
In a right triangle there is only one acute angles.

One of them.
A trapezoid can have either two, one, or no right angles (90 degrees), depending on its specific shape. For instance, a right trapezoid has one pair of parallel sides and one pair of right angles, while an isosceles trapezoid typically has no right angles. Thus, the number of right angles in a trapezoid can vary.
There are four right angles in a rectangle.

There are four right-angles (90 degrees), one in each corner of the square.
One right angle = 90 degrees so 180 degrees = 2 right angles.
