Question

An inclined transversal passes through two vertical parallel lines labeled upper M and upper N. The angles formed around the intersection point of upper M are labeled clockwise, starting from the upper left quadrant: 1, 2, 4, and 3. The corresponding angles formed around the intersection point of upper N are labeled clockwise, starting from the upper left quadrant: 5, 6, 8, and 7.

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

Angle 4 and angle 5 are vertical angles, so their measures are congruent.
Angle 4 and angle 5 are vertical angles, so their measures are congruent.

Angle 4 and angle 5 are alternate interior angles, so their measures must be the same.

Answer 1

Given that lines M and N are parallel and that angle 4 measures 42°, the reason why angle 5 is also 42° is:

Angle 4 and angle 5 are corresponding angles, so their measures are congruent.

Corresponding angles are formed when a transversal intersects two parallel lines, and they are equal in measure.
