I have got a question regarding making these triangles equal along the trailing edge of the aircraft? I can't seem to make it work it's being drawn of a surface since the file is imported externally
I can't tell for sure by just looking at the screenshot, but you'll probably need to place construction lines connecting the triangles along the wing edge and apply an Equal relation to them.
Is the trailing edge in one plane?
If yes, you should sketch constructionlines between all points and make their length equal (like Glenn said)
If No, you could do the same, but then using a 3d Sketch and convert the trailing edge using 'Convert entities'.
