Answer:
C. An angle congruent to a given angle.
Step-by-step explanation:
We are given a construction in the figure and are required to find which construction is done.
The angles depicted in the figure are known as 'corresponding angles' i.e. the angles having same position at the intersection of two lines.
Now, when two lines are parallel the corresponding angles are always equal.
As, we can see from the figure that there are two parallel lines and a line intersecting both the lines and so, the corresponding angles will be equal.
Hence, the figure shows the construction of an angle congruent to a given angle.
