*congruent*.

For example, let's say there are 2 parametric lines:

s

_{0}( t ) = < 2 , 1 > t + < 0 , - 3 >

s

_{1}( t ) = < -18 , -9 > t + < -6 , -6 >

The loci for both are the same line, just that one proceeds in the opposite as the other (and at a high rate) per change in parameter, and such that

s

_{1}( - t ) = s

_{0}( 9 t + 3 )

Surely, there must be a term for this.
