The graph that demonstrates a transformation that preserves both distance and angle measure is the second option: Two equivalent triangles plotted on a coordinate plane, one in quadrant 1 and one that starts in quadrant 2 and crosses into quadrant 1. This type of transformation is likely a rigid transformation, such as a translation or rotation, which maintains the distance between points and the angle measures.
The other options either involve shapes that are scaled (which do not preserve distances) or are not clear transformations that maintain angles and distances as a rigid motion would.
