Question

(02.06)In the figure below, lines m and n are parallel:

Two parallel lines are shown crossed by a transversal. The angles are labeled with number 1-8. The angles on line m where the line is crossed by the transversal are 1, 2, 3, and 4 in clockwise order from top left. The angles on line n where the line is crossed by the transversal are 5, 6, 7, and 8 in clockwise order from top left.

In the diagram shown, ∠2 measures 77 degrees. What is the measure of ∠4?

5 degrees
77 degrees
103 degrees
180 degrees

Answer 1

Answer:

"77 degrees"

Step-by-step explanation:

If you read the questions carefully, you will see that ∠2 and ∠4 are opposite angles to each other, or vertical angles.

We know that vertical angles are EQUAL to each other.

Hence,

∠4 = ∠2  [which is 77]

So, ∠4 = 77°

Answer 2

That is actually wrong. I think it is C.
