Question

Is it always true that dilations of a triangle are congruent to the original triangle

Answer 1

Description
DescriptionIn mathematics, a dilation is a function from a metric space into itself that satisfies the identity for all points, where is the distance from to and is some positive real number. In Euclidean space, such a dilation is a similarity of the space. Dilations change the size but not the shape of an object or figure. Wikipedia

Answer 2

A dilation is a transformation that changes the size but not the shape of a figure. Therefore, the image created by the dilation is not congruent to the pre-image, the original figure; it is similar. ... The scale factor of a dilation is the ratio of a length in the image to the corresponding length in the pre-image.
