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.

∙ 10y agoYes, 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.

Are two obtuse triangles sometimes always or never similar?
sometimes
Are equilateral triangles equiangular?
Yes, all the angles of an equilateral triangle are always 60 degrees.
Does triangular prisms always have two bases that are equilateral triangles?
yes, they do ,because they have two bases that are equilateral triangle and three faces that are rectangles.
Are Equilateral and equivalent triangles the same thing?
No Equilateral triangles are triangles that have all of its three sides the same exact measurement. This means that if all the sides are the same then all of the interior angles will equal the same. And they always equal 60 degrees in an equilateral triangle. Equivalent traingles are just traingles that are equal in size and angles to another triangle equal. Equivalent traingles can be equilateral but they do not have to be.
Are 2 equilateral triangles always congruent?
No. A triangle with 2-inch sides is not congruent with a triangle with 3-inch sides.
Two equilateral triangles are sometimes similar?
Two equilateral triangles are always similar!
Are two obtuse triangles always similar?
Not always, sometimes two obtuse triangles are similar and sometimes they are not similar.
Which types of 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.
Is an altitude always sometimes or never an angle bisector?
sometimes, the altitude of isosceles triangles resting on their base and equilateral triangles are angle bisectors
Are two obtuse triangles sometimes always or never similar?
sometimes
Are two arbitrarily chosen equilateral triangles similar?
Yes. Corresponding angles of the two triangles are always equal, and lengths of corresponding sides are always in the same ratio.
Are a scalene triangle and an isoceles triangles sometimes always or never similar?
Sometimes similar but it depends
Are Two isosceles triangles are sometimes always or never similar to each other?
Sometimes.
Is two equilateral triangles always equal?
lol
Are equilateral triangles equiangular?
Yes, all the angles of an equilateral triangle are always 60 degrees.
Are some right triangles are also equilateral triangles?
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.
What polygon is always regular?
Squares, rhombera, and equilateral triangles are always regular.
