Are two equilateral triangles sometime always or never similar to each other?
Yes, two equilateral triangles are always similar to each other. They have the same number of sides, the same angles and the lengths of the sides between the two triangles are always in the same ratio.
Is two squares always sometimes or never similar?
Yes
Are two equilateral triangles sometimes always or never similar to each other?
Since triangles have three sides and must have interior angles equal to pi or 180o, the three interior angles in all equilateral triangles will be pi/3 or 60o.However, equilateral triangles must also have equal side lengths. Since equilateral triangles with interior angles of 60o will not necessarily have the same side lengths, two equilateral triangles will sometimes be similar to each other.
Are two regular octagons always sometimes or never similar?

Are two congruent pentagons either always sometimes and never similar?
