All equilateral triangles are similar.
In an equilateral triangle, all the lengths of the sides are equal.
In such a case, each of the interior angles will have a measure of 60°
Since the angles of an equilateral triangle are the same, it is also known as an equiangular triangle.
A property of equilateral triangles includes that all of their angles are equal to 60°
The AAA Triangle Similarity Postulate asserts that if all of the angles in a triangle are equal to the corresponding angles in another triangle, then those two triangles are equal.
Since every equilateral triangle’s angles are, 60°every equilateral triangle is similar to one another due to this AAA Postulate.
=> For congruence of triangles, we need equal sides for two equilateral triangles, but here it has said nothing about sides of both triangles in Congruent. So, this is incorrect. Here, it can be said that all equilateral triangles are similar.
Hence, all equilateral triangles are similar.
