Geometry

Question Analysis:
This question assesses knowledge of exterior angles in regular polygons.

Key Concept Explanation:
The sum of all exterior angles of any polygon (one per vertex) is always 360°.
For a regular polygon, all exterior angles are equal, so each measures 360° ÷ number of sides.

Step-by-Step Solution:
A regular hexagon has 6 sides.
Each exterior angle = 360° ÷ 6 = 60°.

Option Analysis:
A) 60°: Correct. Matches the calculation for a hexagon.
B) 72°: Incorrect. This is the exterior angle of a regular pentagon (360° ÷ 5).
C) 90°: Incorrect. This applies to a square (360° ÷ 4).
D) 120°: Incorrect. This is the measure of each interior...
