, creating intersections at E and F. Each pair of exterior angles are outside the parallel lines and on the same side of the transversal. There are thus two pairs of these angles. In the figure above, click on 'Other angle pair' to visit both pairs of exterior angles in turn.

If the transversal cuts across parallel lines (the usual case) then alternate exterior angles have the same measure. So in the figure above, as you move points A or B, the two alternate angles shown always have the same measure.

Angles formed by Transversal and parallel lines. Formula for same side interior, same side exterior, corresponding angles. ... Same Side Interior (in greater Depth) ; Same Side Interior angles are the angle pairs that are on the insides of the two lines (the interior) and on the same side of the transversal.

For any pair of parallel lines 1 and 2, that are both intersected by a third line, such as line 3 in the diagram below, angle A and angle D are called alternate exterior angles. Alternate exterior angles have the same degree measurement.

Consecutive exterior angles (same-side exterior angles) are exterior angles on the same side of the transversal. In Figure 2 , ∠l and ∠8 are consecutive exterior angles. Also, ∠2 and ∠7 are consecutive exterior angles.
