12 SIDES

All polygons can be divided up into triangles by joining one vertex to all of the other vertices.

The number of triangles is always two less than the number of sides.

If you know the number of triangles you add 2 to find the number of sides.

Every triangle has 180°

Number of triangles: 1800 /180 = 10 triangles

Number of sides: 10+2=12 sides
