Question

what is the angle a line makes with itself?​

Answer 1

Answer:

The angle of inclination of any line which is parallel to x-axis or x-axis itself is 0 degree. The angle of inclination of any line which is parallel to y-axis or y-axis itself is 90 degrees.

Answer 2

Answer:

180°

A straight angle always forms a straight line. The value of the straight angle is 180°. The arms of the straight angle lie opposite to each other from the vertex point. The straight angle measured anticlockwise is the positive straight angle i.e.180°.
