Question

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.

Answer 1

I do not believe any of these answers are correct. There is a formula to follow in order to know the sum of the interior angles of a polygon. Unless, you use the formula, and the interior angles are 360 degrees, than D would be the right answer.

Answer 2

The answer is d. Marco's statement is correct and contains no ERROR
