What are consecutive interior angles?

are called Consecutive Interior Angles. d and f are Consecutive Interior Angles. c and e are Consecutive Interior Angles. When the two lines are parallel, any pair of Consecutive Interior Angles add to 180 degrees.

Are consecutive angles equal to each other?

A pair of angles formed on each side of the transversal when it interacts with two parallel lines are known as consecutive angles. The angles in the same region (either interior or exterior) on each of the parallel lines form consecutive angles pairs. Do Consecutive Angles Equal Each Other? No, consecutive angles are not equal to each other.

What is the proof of consecutive angles theorem?

Consecutive angles theorem or consecutive interior angles theorem states that "Two consecutive interior angles are always supplementary angles". In other words, two interior consecutive angles always add to 180°. Let us look at the proof of consecutive angles theorem. From the above two equations, ?E + ?F = 180°.

Are C and F interior angles?

While the pair of angles, ?c and ?f, are interior angles, they are not found on the same side. Now, taking a look at C: ?d and ?f are interior angles lying on the same side confirming that the two are consecutive interior angles. This shows that C is the correct answer.
