(a) obtuse angle
(b) one - degree angle
(c) right angle
(d) semicircle

Explanation:

Step1: Recall angle - circle relationship

A full - circle has 360 degrees.

Step2: Define a one - degree angle

An angle that turns through $\frac{1}{360}$ of a circle is defined as a one - degree angle.

Step3: Analyze other options

An obtuse angle is greater than 90 degrees and less than 180 degrees. A right angle is 90 degrees. A semi - circle corresponds to 180 degrees.
