Question

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

Answer 1

m∠4

m∠8

m∠6

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
