This is something you have to remember. When you have two parallel lines and another line intersects the two, then the angle formed is the same if at the same position. so angle 3 = angle 7
The measure of ∠3 is also 79°. They are both corresponding angles.
Step-by-step explanation:
Since both ∠7 and ∠3 are on the same side of the transversal and are formed by two parallel lines, they consist of the same measurement.
They are known as corresponding angles because they are on the same side of the transversal, however, one angle is interior (∠3) and the other is exterior (∠7).
