__________ are pairs of angles formed when a third line (transversal) intersects two other lines. These angles are on the opposite sides of the transversal and are between the other two lines.

Respuesta :

"Opposite sides of the transversal..." Alternate

"Between the other two lines." Interior

Alternate Interior angles.

If they were outside the two lines they would be alternate exterior angles and if they were on the same side of the transversal then they would be corresponding angles.
