Two triangles can be formed by the diagonals of one vertex of a four-sided polygon.
It is: 8-2 = 6 triangles
An angle is formed at each vertex of a polygon.
A straight line that joins one vertex to another vertex.
A line that joins any vertex of a polygon (or polyhedron) to any vertex other than itself or adjacent ones is a diagonal.

A diagonal of a polygon is a segment drawn from one vertex to another non-adjacent vertex in a polygon. This leaves 32 diagonals that can be drawn from one vertex in a 35 sided polygon.
It is: 8 because 8 triangles make up a 10 sided polygon
It is a pyramid
