Equilateral triangles are 60-60-60 degree triangles, all 3 sides are equal in length. Is this the triangle you are working with?
I have the best luck with leaving the points on them. This tip was in the One Block Wonder book and it really works.
If the points are already clipped, you can lay one triangle right over the next one matching all sides.
