Alternate Exterior Angles Help

The term alternate exterior angles is often used when two lines are cut by a third line, a transversal.

In the figure above, line $t$ is a transversal cutting lines $k$ and $l$ , and there are two pairs of alternate exterior angles:

$∠ 1$ and $∠ 7$

$∠ 4$ and $∠ 6$

The Alternate Exterior Angles Theorem states that if $k$ and $l$ are parallel, then the pairs of alternate exterior angles are congruent. That is,

$∠ 1 ≅ ∠ 7$ and $∠ 4 ≅ ∠ 6$ .

The converse of this theorem is also true, and math helper online could do it for you.
