Are all equilateral triangles similar? Explain your answer please?
All equilateral triangles are similar.
A property of equilateral triangles includes that all of their angles are equal to 60 degrees.
The AAA Triangle Similarity Postulate states 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 degrees, every equilateral triangle is similar to one another due to this AAA Postulate.
