When two lines are parallel, the distance between them is _____A.Always equalB.Not equalC.IncreasesD.None of these

The correct answer is A. Always equal.

Explanation:

When two lines are parallel, they are equidistant from each other at every point. This means that the perpendicular distance between them remains constant and does not change, regardless of where you measure it along the lines. Therefore, the distance between two parallel lines is always the same (equal).

This is a fundamental property of parallel lines in Euclidean geometry. The lines never intersect and maintain a constant distance throughout their length.
