A regular decagon can be divided into triangles by drawing diagonals from one vertex to all other non-adjacent vertices. This method results in a total of 8 triangles. Alternatively, using the formula for the number of triangles formed in a polygon, which is ( n - 2 ) (where ( n ) is the number of sides), a decagon (10 sides) can be divided into ( 10 - 2 = 8 ) triangles.
