Question

tell whether this argument is a valid or invalid deduction. parallel lines are lines that are coplanar and never intersect. lines ℓ and m never intersect. therefore, ℓ || m. after you pick your answer press go. valid invalid go

Explanation:

The definition of parallel lines requires two conditions: being coplanar and never intersecting. The argument only states that lines \( \ell \) and \( m \) never intersect, but it does not confirm that they are coplanar. Since one of the necessary conditions for parallel lines is not verified, the deduction that \( \ell \parallel m \) is invalid.

Answer:

Invalid
