Given:
A figure of an angle.
To find:
The parts of the angle.
Solution:
From the given figure, it is clear that the vertex point of the given angle is I.
The starting point of two rays is point I.
First ray is starting from the point I and passes through the point J. So, the name of ray is
.
Second ray is starting from the point I and passes through the point H. So, the name of ray is
.
Two parts of the given angle are
and
.
Therefore, the correct options are D and F.
