In the following diagram, m||n. State all the angles that are equal in measure to angle 1 and state why.

Answer:
m∠4
m∠8
m∠6
Step-by-step explanation:
we know that
If line m is parallel to line n
then
m∠4=m∠1 -----> by vertical angles
m∠8=m∠1 -----> by corresponding angles
m∠6=m∠1 -----> by alternate interior angles
