Twilight, having been called on by Pinkamena Pie, finds herself becoming obsessed over something so small as a triangle that makes no sense. Though Rainbow Dash and Pinkie Pie may find her anxiety over this to be hilarious, they are glad to help her come to the bottom of things.
So... The triangles are adding up to 190. I see three possible answers:
A prank involving modified protractors
a prank involving Discord's assistance
Somehow, Euclidean Geometry has actually been modified for real.
5616531 How long did it take you to think of that? Because that first one is absolutely correct.
5616552 I am a bit of a math nerd. I actually thought of the Discord one first.
If Twilight is an alicorn in this, then actually, I am going to PM that idea to you.
5616567 Oh crap, you just reminded me that from now on, if I want to use Twilight, I will need to clarify whether it is Twilicorn or not... That makes it hard for me to obscure where in the time line the story takes place. Well anyway, I cannot wait to recieve this idea you have.
She doing it on a sphere. Only on a plane does 3 sides of a triangle equal 180. if she was doing it on the inside of a sphere it would be less than 180
Are we dealing with Discordian geometry?

It would be greater than 180, actually. It's a standard result of spherical geometry that the sum of the interior angles of a spherical triangle is greater than 180 degrees by an amount directly proportional to the solid angle the triangle subtends.
