If angle 4 is 42° and lines M and N are parallel, give a reason why angle 5 is also 42°

Answer 1

If lines M and N are parallel, we can use the property of alternate interior angles. Since angle 4 is 42° and it is an alternate interior angle with angle 5 (formed by a transversal crossing the parallel lines), we can conclude that angle 5 is also 42°.

Thus, the reason is: Angle 5 is equal to angle 4 because they are alternate interior angles formed by a transversal intersecting parallel lines M and N.
