Not too sure about the given description but they could be equal alternate angles.
Alternate int angles are two interior angles which lie on different parallel lines and on opposite sides of a transversal
A transversal line cuts through parallel lines forming equal corresponding angles
Alternate angles are equal and lie on opposite sides of the transversal line that cuts through the parallel lines
No. Corresponding angles are only equal when the lines crossed by the transversal are parallel.
Angles on opposite sides of the transversal and between the parallel lines
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.
Those are "alternate interior" angles. They're always equal.
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 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.
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.
Alternate Exterior 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.
A basic knowledge of angles when two parallel lines meet a transversal is necessary.
