In which diagram do angles 1 and 2 form a linear pair?

A
Image with description 2 rays emerge from the center of the horizontal line. Angles are labeled from left to right as 1, 2, and 3.
B
Image with description Two lines intersect at a point. The vertical angles are named as 1 and 2, respectively.
C
Image with description Angles 1 and 2 have a common vertex and a common side. They both lie in a straight line.
D
Image with description 3 rays emerge from a common vertex point to form two angles. Angles are labeled as 1, and 2. Both angles add up together to form a right angle.

Which diagram shows lines that must be parallel lines cut by a transversal?

A
Image with description Parallel lines are intersected by a transversal line. The first line intersecting the transversal line creates 4 angles, the top right angle is labeled as 115 degrees. The second line intersecting the transversal line creates 4 angles, the top left angle is labeled as 115 degrees.
B
Image with description Parallel lines are intersected by a transversal line. The first line intersecting the transversal line creates 4 angles, the bottom left angle is labeled as 115 degrees, and the bottom right angle is labeled as 65 degrees.
