The drawing of two triangles facing away from each other illustrates the concept of reflection. This geometric transformation involves flipping a shape over a line (known as the line of reflection) to create a mirror image. When two triangles face away from each other, it effectively demonstrates that they are mirrored across a central axis between them.

Reflection retains the original shape's size and angle measures but reverses the orientation of the shape. In the context of the triangles, the reflection may represent a symmetrical relationship where each side has a point that corresponds to another point in the opposite triangle, thus emphasizing the concept of mirroring inherent to reflection.

In contrast, translation would involve sliding the triangles along a plane without altering their orientation. Rotation would mean turning the triangles around a specific point, changing the direction they face while keeping them congruent. Dilation involves resizing the triangles either by enlarging or reducing them, which does not apply to the scenario of two triangles facing away from one another.
