Short Answer
A regular octagon has eight equal sides, with each interior angle measuring 135 degrees, totaling 1080 degrees for all interior angles. The exterior angles of a regular octagon are each 45 degrees, while for a regular hexagon, each exterior angle measures 60 degrees.
Step 1: Understanding Octagon Angles
To grasp the characteristics of a regular octagon, note that it has eight equal-length sides. This symmetry allows us to determine both the exterior and interior angles. Each interior angle of a regular octagon measures 135 degrees, contributing to a total of 1080 degrees for all interior angles combined.
Step 2: Calculating Exterior Angles of an Octagon
The exterior angles of a regular octagon are equally distributed due to its symmetrical properties. Each exterior angle is calculated by dividing the full angle of a circle among the sides:
- Exterior Angle = 360 degrees / 8 sides
- Each Exterior Angle = 45 degrees
Step 3: Exploring Hexagon Angles
When analyzing a regular hexagon, which has six equal sides, it also possesses equal exterior angles. To determine the measure of each exterior angle:
- Calculate by dividing the full circle: 360 degrees / 6 sides
- Each Exterior Angle = 60 degrees
Understanding these angle measurements helps in various geometry applications.
