I assume the question refers to a right angled triangle, since a rigt angle, by itself, cannot have an area.
There are three possible answers - depending upon which of the sides are "a" and "b".
Case 1: The right angle is between the sides "a" and "b". The area is 0.5*a*b
Case 2: The side "a" is opposite the right angle (the hypotenuse). Then the third side, c is sqrt(a2-b2). The area is 0.5*b*c
Case 3: The side "b" is opposite the right angle (the hypotenuse). Then the third side, c is sqrt(b2-a2). The area is 0.5*a*c
-- an angle that measures 90 degrees -- an angle whose sides are mutually perpendicular
no. if it did it wouldent be a circle a circle can circumscribe a right angle a right angle whose vertex lies on a circle has sides that intersect the circle's diameter.
An inscribed angle is an angle whose vertex is on the circle and whose sides are chords.
central angle
A single ray.
a right angle, or a 90 degrees angle
-- an angle that measures 90 degrees -- an angle whose sides are mutually perpendicular
In any right triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares whose sides are the two legs (the two sides that meet at a right angle).

central angle
If the triangle contains an angle whose measure is equal to 90 degrees or if the sum of the squares of two of the sides equals the square of the third. Essentially, if it has a right angle or if a2 + b2 = c2 where c is the longest side of the triangle and a and b are the other two sides, then the triangle must be a right triangle (in Euclidean geometry, that is)
Inscribed angle
The measure of an angle whose sides overlap is 0 degrees. It is than not an angle, but rather a line.
An inscribed angle.
