Atransformation of δstv results in δutv. which transformation maps the pre-image to the image? dilation reflection rotation translation

Notice that tv is in the original triangle and in the image. that means that we are looking for a transformation where this segment remains fixed (doesn’t move) which is the case when doing a reflection. a reflection over the line segment tv would leave that segment unchanged. think of having the triangle iba page and picking p vertex s swinging it over tv and having it land on the other side. tv the line of reflection remains fixed while s moves to a new point here called u.
