Question

(a) ángulos correspondientes: ∠y∠ (b) ángulos alternos internos: ∠y∠ (c) ángulos alternos externos: ∠y∠

Explanation:

Step1: Corresponding angles

Corresponding angles are in the same relative position. So, $\angle1$ and $\angle5$, $\angle2$ and $\angle6$, $\angle3$ and $\angle7$, $\angle4$ and $\angle8$ are corresponding angles.

Step2: Alternate - interior angles

Alternate - interior angles are between the two lines and on opposite sides of the transversal. So, $\angle3$ and $\angle6$, $\angle4$ and $\angle5$ are alternate - interior angles.

Step3: Alternate - exterior angles

Alternate - exterior angles are outside the two lines and on opposite sides of the transversal. So, $\angle1$ and $\angle8$, $\angle2$ and $\angle7$ are alternate - exterior angles.

Answer:

(a) $\angle1$ y $\angle5$, $\angle2$ y $\angle6$, $\angle3$ y $\angle7$, $\angle4$ y $\angle8$
(b) $\angle3$ y $\angle6$, $\angle4$ y $\angle5$
(c) $\angle1$ y $\angle8$, $\angle2$ y $\angle7$
