Alternate Interior Angles
Yes, the opposite rays of vertical angles are always coplanar, so the angles are as well.
Alternate Interior Angles
They are angles formed by the transversal line cutting through parallel lines
corresponding and alternate angles
No. Angles are not congruent. (Triangles may be congruent.)
Two pairs of alternate opposite angles
corresponding angles
Alternate Exterior Angles :)
Angles on opposite sides of the transversal and between the parallel lines
Yes, the opposite rays of vertical angles are always coplanar, so the angles are as well.
Yes
They are equal alternate angles
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.
Alternate interior angles.
Those are "alternate interior" angles. They're always equal.
