Question

In the diagram, lines m and n are parallel. If m∠2 = 150°, find the measure of the angle.

Answer 1

∠4 = ?

Answer 2

What type of angles are angles 4 and 2 with respect to two parallel lines cut by a transversal. You need to know that to select the theorem that gives the numerical relationship between the two angles.

Answer 3

Thanks

Answer 4

@Infinyte What did you get for the answer? What kind of angles are angles 2 and 4?

Answer 5

that would mean that its 150 right?

Answer 6

sorry, 120

Answer 7

they're obtuse

Answer 8

Yes, it would mean that its 150 right?

Angles 2 and 4 are corresponding angles formed by a transversal that cuts two parallel lines.
Theorem (Postulate in some texts) : If two parallel lines are cut by a transversal, corresponding angles are congruent.
Bottom Line: They have the same measure.
