How do I control bullet angles

So I have a triangle spinning and from each of it's corners it shoots a bullet and I want them to shot out of the corners at the same angle that the corners are pointing, how can I do that?

The triangle is rotating, so I'm assuming the originpoint is in the center..

Place imagepoints at the corners..

for imagepoint 1:

on bullet created - set angle = angle(triangle.x,triangle.y,triangle.imagepointx(1),triangle.imagepointY(1))

etcetera..

or....you can always add more image points <img src="{SMILIES_PATH}/icon_e_smile.gif" alt=":)" title="Smile">

but they are not necessary <img src="{SMILIES_PATH}/icon_e_biggrin.gif" alt=":D" title="Very Happy">

I do have image points set at each point in the triangle but the only go in 2 directions instead of making a spray all around coming from the points of the triangle

..if you want something like this

and see how it was done

Also is there anyway I could make this triangle move around the player once it spawns in while it spins? and yes that's exactly what I want, thank you
