Ok.
Take a 5 pointed star. It has 5 triangles (one at each point). Now this is what you have to do: You can draw 2 STRAIGHT lines through it anywhere you like, giving it more triangles. Like this:

The object is to come up with 10 triangles from two lines drawn through the star. Good luck. All of my smartest kids cant do it, but apparently its possible. Dont look up the answer on the internet. I admit ive tried researching the answer, to no avail though.

a hint on one possibility:

avoid the central pentagon

(actually, i haven't done the leg work, but i'm pretty sure the it's a red herring)

You're all a bunch of cheating ******! Am I the only one that did it by myself?

I added two lines and get 22 triangles.

Technically you could say there's also three huge triangles if you allow for line dissection

I got it on the first try without cheating. Maybe you're overthinking it.
