The first answer here was "There are none." However, if you use Thales' Theorem, you will find that the number of right angles are actually close to infinite.
Thales' Theorem states that if points A, B and C are on the circumference of a circle, where the line AC is the diameter of the circle, then the resulting triangle will be a right triangle. As long as point B does not land on the same spots as points A or C, then no matter where point B is, you will have a right triangle. And wherever you have a right triangle, you'll always have a right angle.

What are the different types of angles in a circle?
There are many angles inside a circle. You have inscribed angles, right angles, and central angles. These angles are formed from using chords, secants, and tangents.

How many right angles do a semi circle have?
A semicircle itself does not have any right angles; it is a half-circle. However, if you consider the angle formed at the endpoints of the diameter when a line is drawn to any point on the arc of the semicircle, that angle is a right angle (90 degrees). Thus, while the semicircle itself has no right angles, it can form right angles with lines drawn to points on its arc.
