Question

Help me pls

Tell whether lines m and n must be parallel from the given
Information. If they are, state your reasoning.

Answer 1

First one isn’t second one is

Answer 2

The first one isn't the second one is.

Explanation:

In the first one, they have to be equal because they're corresponding angles so m and n are parallel.

In the second one, m<2 and m<3 would be supplementary and add up to 180 degrees if the lines were parallel and since they don't add up to 180, the lines are not parallel.
