Which best explains why all equilateral triangles are similar? all equilateral triangles can be mapped onto each other using dilations. all equilateral triangles can be mapped onto each other using rigid transformations. all equilateral triangles can be mapped onto each other using combinations of dilations and rigid transformations. all equilateral triangles are congruent and therefore similar, with side lengths in a 1: 1 ratio.

The correct answer is:

All equilateral triangles can be mapped onto each other using dilations.

The reason that best describes the reason why all equilateral triangles are similar is:

All equilateral triangles can be mapped onto each other using dilations.

Two figures that have the same shape are said to be similar. When two figures are similar, the ratios of the lengths of their corresponding sides are equal.

In reflection, rotation and translation  and there combinations the location of shape of the figure might appear different.

Hence we could not say that they are similar.
