To create an octadecagon (18-sided polygon), each internal angle should measure 150 degrees, as calculated by the formula for the internal angle of a regular polygon: ((n-2) \times 180° / n), where (n) is the number of sides. The external angle, which is the cut angle needed to form the sides, is 30 degrees (180° - 150°). Thus, when constructing an octadecagon frame, you would make angle cuts of 30 degrees at each vertex.

What is the interior and exterior angle of a 18 sided shape?
For an 18-sided polygon (octadecagon), the formula to calculate the interior angle is ((n-2) \times 180° / n), where (n) is the number of sides. Substituting (n = 18), the interior angle is ((18-2) \times 180° / 18 = 160°). The exterior angle can be found using the formula (360° / n), which gives (360° / 18 = 20°). Therefore, each interior angle is 160° and each exterior angle is 20°.
