A duo-decagon (also known as a dodecagon) is a 12-sided polygon. The formula to find the number of triangles in a polygon is n(n-3)/2.
So, if n = 12, the equation becomes
12(12-3)/2 = 12(9)/2 = 54
There are 54 triangles in a duo-decagon.
So, if n = 12, the equation becomes
12(12-3)/2 = 12(9)/2 = 54
