Those are "alternate interior" angles.
They're always equal.
Angles on opposite sides of the transversal and between the parallel lines
Yes
Parallel lines can have a line crossing both of them. They call that the transversal. Corresponding angles are on the same side of the transversal. Alternate are on opposite sides of the transversal.
Alternate Exterior Angles are created where a transversal crosses two (usually parallel) lines. Each pair of these angles are outside the parallel lines, and on opposite sides of the transversal.
When two parallel lines are cut by a transversal, the two pairs of angles on opposite sides of the transversal and outside the parallel lines, and the angles in each pair are congruent.
Angles on opposite sides of the transversal and between the parallel lines
Yes
Not too sure about the given description but they could be equal alternate angles.
Parallel lines can have a line crossing both of them. They call that the transversal. Corresponding angles are on the same side of the transversal. Alternate are on opposite sides of the transversal.
I think it is when there are 2 parallel lines, then the lines which cut both is called transversal.so, the angles which are between one side of the transversal and a parallel line must be called a transversal angles.

Alternate Exterior Angles :)
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.
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.
A basic knowledge of angles when two parallel lines meet a transversal is necessary.
