Question

Which two pairs are consecutive interior angles?

A) 15 and 10
B) 7 ans 11
C) 2 and 10
D) 7 and 8
E) 1 and 9
F) 6 and 7

Answer 1

option B

Explanation:

"the pair of angles on one side of the transversal and inside the two lines are called the consecutive interior angles."

so its 7 and 11

Answer 2

B(7 and 11), F(6 and 7)

Explanation:

You want to identify the pairs of angles that are consecutive interior angles in the given figure.

Interior angles

Where a pair of lines is crossed by another line, the "interior" angles are those that are between the pair of lines. In the given figure, the only angles that are not "interior" to one or the other pairs of lines are angles 1, 4, 13, and 16.

Consecutive

"Consecutive" angles are angles that lie on the same side of a line. In this figure, angles 1 and 4 are "consecutive" exterior angles, even though they are not adjacent to one another.

Pairs of consecutive interior angles in this figure are ...

(2, 3), (6, 7), (10, 11), (14, 15), (5, 9), (6, 10), (7, 11), (8, 12)

The bolded pairs are among the answer choices.

Additional comment

"Consecutive" angles are also called "same-side" angles, because they lie on the same side of the line containing the rays that form them.
