Given only the information in the diagram, determine if m is parallel to n. If so, name the postulate or theorem used to support
Advocard [28]

Answer:

<em><u>From my research on the internet, the image attached supports this problem. The two lines are parallel, as supported by the converse of corresponding angles postulate. It states that: If a transversal intersects two lines and the corresponding angles are congruent, then the lines are parallel.</u></em>
