How to solve ratio problem

Answers:

Top left pic: Alternate exterior

Top right pic: None of them

Middle left pic: Corresponding

Middle right pic: Alternate interior

Bottom pic: Corresponding

Explanation:

The transversal is the line that goes through the other 2 lines.

Alternate angles are on opposite sides of the transversal:

Alternate exterior angles are on   Alternate interior angles are onopposite sides of the transversal         opposite sides of the transversal                                                   and on the outside part of the lines.     and on the inside part of the lines.

Corresponding angles are on the same side of the transversal.

But, the 2 angles have to be on the same side of the lines it's on.

For example, in the picture below, figure 2 has the numbers on top of both lines. Figure 3 has the numbers on bottom of both lines. But, figure 1 has number 1 on top of the line and number 2 on the bottom of the line. So that's why figure 1 is "none of these."
