Question

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

Explanation:

Step1: Identify Alternate Exterior Angles

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

Step2: Identify Corresponding Angles

Corresponding angles are in the same relative position. So, $\angle5$ and $\angle7$ are corresponding angles.

Step3: Identify Alternate Interior Angles

Alternate interior angles are non - adjacent and on opposite sides of the transversal inside the two lines. So, $\angle2$ and $\angle7$ are alternate interior angles.

Answer:

(a) $\angle1$ y $\angle8$
(b) $\angle5$ y $\angle7$
(c) $\angle2$ y $\angle7$
