Answer this question… half
180 degrees, if you mean a half circle
It is the consequence of one of the circle theorems and in some books, it is considered a theorem itself. The underlying proposition is that the angle subtended at the circumference of the circle by any arc of a circle is half the angle subtended at the centre. In the case of a semicircle, the arc is the half circle and the angle at the centre is the one that the diameter makes at the centre of the circle ie 180 degrees. So the angle at the circumference is half that ie 90 degrees.
A straight angle is a half circle.
A semi-circle, half a circle, by definition is 180 degrees, half of a rotation. A whole circle has a whole rotation, which is 360 degrees.
180 degrees.
Half of a revolution of a circle is 180 degrees and its angles added together are supplementary.
A protractor can be used to measure an angle. An angle is basically part of a circle. A complete circle is 360 degrees. A right-angle is 90 degrees, half a circle is 180 degrees, and so on.
180o is basically a straight angle, if 360 was a circle 180 wiuld be a half circle
another name for a half circle is semi-circle
