This is the same regardless of how many sides the polygon has. The exterior angles of a triangle add up to 360°; the exterior angles of a decagon also add up to 360°. Exterior Angle Sum of a Polygon = 360 degrees Suggested Reading How to Find Pi Using Regular Polygons An article a...
Sum of Interior Angles = (n−2) × 180° Each Angle (of a Regular Polygon) = (n−2) × 180° / nPerhaps an example will help:Example: What about a Regular Decagon (10 sides) ? Sum of Interior Angles = (n−2) × 180° = (10−2) × 180° = 8 × 180° = 1440°...

(the first embodiment) shown at FIG. 1cin FIG. 1. Thus the decagon shape would be interlockable both vertically and horizontally. However, decagon shaped game pieces would not allow words to be made up by interlocking placing said pieces next to each other along a vertical axis because the...
