Two pairs.
you are stupid and ugly
When 2 parallel lines are cut by a transversal some of the pairs of angles which are formed are called alternate angles whereas other pairs are called interior angles.
Corresponding angles
Corresponding angles are equal and are formed when a transversal line cuts through parallel lines
Yes.
Providing that the lines are parallel that the transversal passes through then it will have two equal alternate angles that are on opposite sides of the transversal.
true
If the transversal is at right angles, then all the angles will be right angles. If not, there will be only two different measures between the eight angles formed. These will alternate.

The angles that share a vertex and a side of a transversal but no interior points are called vertical angles. Vertical angles are formed when two lines intersect, and they are always congruent.
When 2 parallel lines are cut by a transversal some of the pairs of angles which are formed are called alternate angles whereas other pairs are called interior angles.
More info needed. Are the 2 lines parallel, perpendicular, or? are the angles that you are interested in on opposite sides of the intersecting line or the same side. The intersecting line is called a transversal. If the original lines are parallel, angles between the 2 lines on opposite sides of the transversal are called alternate interior angles, etc.
Two pairs of alternate opposite angles
Sure. Just as long as the transversal is perpendicular to the parallel lines.
When two parallel lines are both intersected by a tranversal which is a nonvertical line, otherwise all angles formed by that intersection are right angles.
The alternate interior angle theorem states that when two parallel lines are cut by a transversal, the alternate interior angles formed are congruent. In other words, if two parallel lines are crossed by a third line, then the pairs of alternate interior angles are equal in measure.
That the corresponding angles are equal and that the alternate angles are equal and that angles on a straight line add up to 180 degrees.
