by using rightangle triangle
360 degrees in a circle, so 180 degrees in a half turn.
Its really just half of half of 90deg. half of 90 is 45 and half of 45 is 22.5. therefore the answer being 22.5deg
One half of a right angle is a 45 degree angle.
540
it is a turn in gymnastics and you go around one full time then a half ps. hi brianna ahahahahahahah
A right turn is 90 degrees, and half that is 45 degrees. A right turn and half another turn is 90 plus 45 degrees, or 135 degrees. Provided the turns are in the same direction, that is.
