Answer:
A). ∠ 1 \angle 1 ∠1 and ∠ 8 \angle 8 ∠8 are a pair of alternate exterior angles.
B). ∠1 and ∠5 are a pair of corresponding angles. Similarly, ∠2 and ∠6, ∠3 and 7, and ∠4 and ∠8
C). ∠3 ≅ ∠60°
Explanation:
A) both angles are located outside lines s and h, are not adjacent to each other, and are on opposite sides of the transversal.
B). The Corresponding Angles Postulate states that if k and l are parallel , then the pairs of corresponding
C). are also corresponding angles.
D)
For example, ∠4 and ∠6 are corresponding angles, therefore they are congruent. Other pairs of corresponding angles include ∠3 and ∠5, ∠1 and ∠7, and ∠2 and ∠8. Vertical Angles are formed by angles that are opposite of each other.
