a right angle has 3 angles on it please.
well you know what a right angle looks like? well its not half of that. however half of a right angle is 45 degrees so close to 42
Bigger than 90 (a right angle), less than 180 (a straight line).
It is an acute angle that is greater than 0 but less than 90 degrees
Very similar to to a 45 degree angle, but a bit smaller. Imagine half of a right angle which is 90 degrees.
