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.
It's a STRAIGHT angle
180 degrees * * * * * No, it is 90 degrees.
you can measure a angle with a protracte.
The measure of the obtuse angle would then be double that of the acute angle.
What does a straight angle measure?
A right angle triangle will fit into a semicircle.
It is a right angle.
A straight angle is 180 degrees, or twice the measure of a right angle. Therefore, it looks like a right angle that has been folded out into a flat line. Another way is to look at the arch of a 180 degree angle as a semicircle. Connect both ends of the semicircle and you have a straight line.
If the arc is circular, such a figure is a semicircle or half circle.

An angle inscribed in a semicircle is called a right angle. According to the inscribed angle theorem, any angle formed by two points on the circumference of a semicircle, with the vertex at the circle's center, measures 90 degrees. This property holds true for any triangle inscribed in a semicircle, confirming that the hypotenuse is the diameter of the circle.
order of rotation of semicircle is 1. angle of rotation of semicircle is 360 degree. If you want to find angle of rotation of a shape, then divide 360 from order of rotation of a shape.
