Which angles are pairs of alternate exterior angles? Check all that apply.

4 lines intersect to form 16 angles. Clockwise from top left, the angles are 1, 2, 3, 4; 5, 6, 7, 9; 9, 10, 11, 12; 13, 14, 15, 16.

In the diagram, which pair of angles are vertical angles?

A transversal intersects 2 lines to form 8 angles. Clockwise from the top, the angles are 1, 2, 3, 4; 5, 6, 7, 8.
Angle 1 and Angle 2
Angle 4 and Angle 6
Angle 6 and Angle 8
Angle 5 and Angle 3

Angle 4 and Angle 6 are vertical angles.

In the diagram, the measure of angle 6 is 98°.

A transversal intersects 2 lines to form 8 angles. Clockwise from top left, the angles are 1, 2, 3, 4; 5, 6, 7, 8.

What is the measure of angle 7?

Angle 7 is also 98°, as angles 6 and 7 are corresponding angles and are congruent when the transversal intersects two parallel lines like in this diagram.

In the diagram, how many angles are alternate exterior angles with angle 16?

4 lines intersect to form 16 angles. The angles created, clockwise from top left are 1, 2, 3, 4; 5, 6, 7, 8; 13, 14, 15, 16; 9, 10, 11, 12.
zero
one
two
three

Two angles, which are angle 2 and angle 14, are alternate exterior angles with angle 16 since they are on opposite sides of the transversal and outside the parallel lines.
