Two equilateral triangles are always similar!
Equilateral triangles are always similar because the will always have sixty-degree angles, and the sides will always have the same 1:1:1 ratio.
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.
Yes. Corresponding angles of the two triangles are always equal, and lengths of corresponding sides are always in the same ratio.
The side are always the same size and length.
Squares, rhombera, and equilateral triangles are always regular.
Yes, all the angles of an equilateral triangle are always 60 degrees.
No because all right triangles have 2 legs and a hypotenuse. The hypotenuse is always longer than either leg so right triangles can't be equilateral triangles.
Not always, sometimes two obtuse triangles are similar and sometimes they are not similar.
