Rewrite the definition ‘parallel lines are equidistant from each other” in biconditional !

To rewrite it in biconditional form, we write it as follows:

Two line are parallel if and only if they are equidistant from each other. 

Biconditionals are true when both statements (facts) have the exact same truth value. Hope this answers the question. Have a nice day.

See below.

Step-by-step explanation:

Use the quadratic function f(x) = -x^2 - 6x. The parabola faces downward with y -intercept (-3,9) and zeros (-6,0) and (0,0). See the attached graph.

The axis of symmetry will serve as a ladder through the coaster at x = -3.
