Question

1. mark a pair of alternate interior angles in red and a pair of corresponding angles in green.

Explanation:

Step1: Recall Angle Definitions

Alternate interior angles: lie between two parallel lines, on opposite sides of a transversal. Corresponding angles: occupy the same relative position at each intersection where a straight line crosses two others.

Step2: Identify Angles

For alternate interior angles (red): Find two angles between the parallel lines, on opposite sides of the transversal. For corresponding angles (green): Find two angles in the same "corner" at different intersections.

Step3: Marking (Visual)

• Red: Locate two angles inside the parallel lines, separated by the transversal (e.g., one above the lower parallel line, left of transversal; one below upper parallel line, right of transversal).
• Green: Locate two angles, e.g., both upper - left at their respective intersections of transversal with parallel lines.

Answer:

(Visual marking: Alternate interior angles marked red, corresponding angles marked green as per the definitions on the given diagram with parallel lines and transversal.)
