Question

(2) Draw octagon and divide it into triangular parts. Tell how many triangles can be made.​

Answer 1

Answer:

Step-by-step explanation:

This can also be figured out as follows: the sum of the interior angles of an octagon is (2n-4)*right angles or (n-2)*triangles. If you want the answer as to the number of triangles formed from each of the vertices, the answer will be 8*6 = 48 triangles.

Answer 2

Answer:

In an octagon, by joining one vertex to the remaining vertices you will get 6 triangles. This can also be figured out as follows: the sum of the interior angles of an octagon is (2n-4)*right angles or (n-2)*triangles.

If you want the answer as to the number of triangles formed from each of the vertices, the answer will be 8*6 = 48 triangles.
