When a regular polygon with n sides is decomposed into triangles using the same vertex, how many triangles are formed? (1 point)
When a regular polygon is decomposed. 27 triangles are formed, where it is the number of sides of the regular polygon. There are twice as many triangles formed than the number of the sides of the regular polygon,
When a regular polygon is decomposed, 2-2 triangles are formed, where x is the number of sides of the regular polygon. There are two fewer triangles than the number of the sides of the regular polygon,
When a regular polygon is decomposed. r triangles are formed, where n is the number of sides of the regular polygon.
When a regular polygon is decomposed, +2 triangles are formed, where x is the number of sides of the regular polygon. There are two more triangles than the number of the sides of the regular polygon.
which one?
