Create pattern - perfectly aligned

[beatles_1a]

Hi Community

I would like to create a pattern as shown in the picture below. I created six triangles and started to lay them out.

But as you can see, it's not really nice aligned. I tried for quite a time but rotate the triangle manually did not get me to the goal.

Any ides how I can align the triangles perfectly?

Thank you!

Hey Mike

Thanks for the hint. I already tried it with some straight lines in the middle.

But same question here how did yout the lines aligned like this (with the star in the middle)?

You're not even doing any basic research on this.

Draw one line, hit the "R" key, hit return, type in your angle, hold alt and hit return the number of "spokes" you want.

I tried to, but couldn't find anything specific.
Anyways thanks a lot for your information!
