That's as maybe.
The mathematical answer is 0, 180 or 360 degrees - depending on whether or not they are all in the same direction.
360 degrees
Four (where each right angle is 90 degrees and a complete turn is 360 degrees.)
In a three-quarter turn, there are three right angles. A right angle measures 90 degrees, so in a full turn (360 degrees), there are four right angles. Therefore, in a three-quarter turn (270 degrees), there are three right angles, as each right angle is 90 degrees.
A right angle turn is equivalent to 90 degrees. Therefore, one ninth of a right angle turn would be 90 degrees divided by 9, which equals 10 degrees. This means that one ninth of a right angle turn is a rotation of 10 degrees.
A right angle is 90 degrees, so 45 degrees is half a right angle turn.
In one full turn, which is 360 degrees, there are exactly four right angles. Each right angle measures 90 degrees, so when you multiply 90 degrees by 4, you get 360 degrees. Therefore, one full turn encompasses four right angles.
45 degrees. A right angle is 90 degrees.
A right angle turn is 90 degrees. A fourth of this would be 90/4 degrees or 22.5 degrees.
A right angle (L) is 90 degrees. A straight angle (_) is 180 degrees.
A right angle is a turn of 90 degrees.
A right angle is 90 degrees, so one-third of a right angle would be 30 degrees.
A right angle is 90 degrees. One fourth of a right angle is, therefore, 90/4 = 22.5 degrees.
