Question

How many triangles can be drawn by joining points of hexagon?

Answer 1

Answer:

Step-by-step explanation:

Assuming a regular hexagon: If you draw all diagonals of a regular hexagon you have 3⋅6=18 possible triangles, but 3 of those are the same (the equilateral triangles) so we have 18−3=15 possible triangles. let me set of this numbers, where in every number corresponds with a number of sides of every polygon.
