An angle subtended at the semicircular arc is 90 degrees.
It is a right angle.
the angle with a value from 90 degree-180 degree
The area is 0.5*pi*r2 where r is the radius. The angle is totally irrelevant since it will always by 180 degrees for a semicircle!
The vector method demonstrates that any angle inscribed in a semicircle is a right angle by using the properties of vectors and the dot product. Let points A and B be the endpoints of the diameter, and C be any point on the semicircle. The vectors AC and BC can be expressed in terms of their coordinates. The dot product of these vectors is zero if the angle ∠ACB is a right angle, which occurs when C is on the semicircle, confirming that any angle inscribed in a semicircle indeed measures 90 degrees.
Yes
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.
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.
A right angle triangle will fit into a semicircle.
It is a right angle.
