8 different things are arranged along a circle. In how many ways can 3 objects be selected such that no two of the selected objects are consecutive.

n different things are arrnaged around a circle. In how many ways can 3 objects be selected when no two of the selected objects are consecutive?

A regular polygon of 10 sides is constructed. Triangles are formed joining vertices of the polygon. Find the number of triangles (i) if two sides of trinangle coincide with the sides of polygon. (ii) if only one side of triangle coincide with the side of polygon.
