Question

identify all pairs of alternate exterior angles. 13 ∠1 and ∠7 ∠2 and ∠7 ∠4 and ∠5 ∠1 and ∠8 ∠3 and ∠6 ∠4 and ∠6 ∠2 and ∠6 ∠3 and ∠7 ∠4 and ∠8

Explanation:

Alternate exterior angles are pairs of angles that lie outside the two lines and on opposite sides of the transversal.

• For \(\angle1\) and \(\angle8\): \(\angle1\) is above the upper - line and \(\angle8\) is below the lower - line, and they are on opposite sides of the transversal.
• For \(\angle2\) and \(\angle7\): \(\angle2\) is above the upper - line and \(\angle7\) is below the lower - line, and they are on opposite sides of the transversal.

Answer:

\(\angle1\) and \(\angle8\), \(\angle2\) and \(\angle7\)
