Alternate Interior Angles Vs Alternate Exterior Angles. Similar to before angles 1 2 7 and 8 are EXTERIOR angles. Click to see full answer.
Angles that are on the opposite sides of the transversal are called alternate angles eg. Interior angles are created in the space inside the parallel lines. Alternate exterior angles are created in the space outside the parallel lines on alternating sides.
If lines are parallel then same side interior angles are supplementary and same side exterior angles are supplementary.
Conversely if two lines are parallel any pair of alternate exterior angles. If lines are parallel then same side interior angles are supplementary and same side exterior angles are supplementary. Click to see full answer. Interior angles on the same side of the transversal are consecutive interior angles.
