Marco says that the interior angles of a triangle add up to 180°. he claims that the interior angles of a hexagon must add up to 360° because a hexagon has twice as many vertices as a triangle and can be divided into two triangles, therefore, its interior angles must sum to twice the value of those of a triangle

which statement, if any, explains marco's e r r o r?

a. a hexagon does not have 6 vertices.

b. a hexagon can be divided into 4 triangles, not 2.

c. the interior angles of a triangle do not add up to 180°.

d. marco's statement is correct and contains no e r r o r.
