Question

The symbol of ___________ consists of two sets of parallel lines of unequal height.​

Answer 1

Answer:

The symbol for parallel lines is ∥, so we can say that A B ↔ ∥ C D ↔ \overleftrightarrow{AB}\parallel\overleftrightarrow{CD} AB ∥CD in that figure. According to the axioms of Euclidean geometry, a line is not parallel to itself, since it intersects itself infinitely often.
