Two squares, a smaller one inside a larger one, are plotted in quadrant 1 of a coordinate plane. The smaller square shares a vertex and two of its sides with parts of two sides of the larger square. The x- and y-axis both range from 0 to 8 in increments of 1.

Two equivalent triangles are plotted on a coordinate plane, one in quadrant 1 and one that starts in quadrant 2 and crosses into quadrant 1. The x-axis ranges from negative 4 to 7 in increments of 1, and the y-axis ranges from 0 to 7 in increments of 1. A line connects a vertex of the triangle in quadrant 2 to the matching vertex of the triangle in quadrant 1.

Two triangles of different sizes are plotted on a coordinate plane. The x-axis ranges from negative 4 to 8 in increments of 1, and the y-axis ranges from negative 4 to 10 in increments of 1.The larger triangle is plotted around the origin and extends into all four quadrants, and the smaller triangle extends between quadrants 1 and 2.

Two rectangles, a smaller one inside a larger one, are plotted around the origin on a coordinate plane. The x-axis ranges from negative 3 to 3 in increments of 1. The y-axis ranges from negative 3 to 5 in increments of 1.

The transformation that preserves both distance and angle measures is an isometry, commonly seen in figures that demonstrate congruence, such as translations, rotations, or reflections.

Among the given options, the one that likely demonstrates this is the set of equivalent triangles (the second option). This option indicates that one triangle exists in quadrant 1 and the other starts in quadrant 2, connecting them with a line. This suggests that the triangles may have been reflected (which is an isometric transformation) without altering their shape or size, thus preserving both distances and angles.

The other shapes (squares and rectangles) could also likely preserve distance and angle measures, but the triangles specifically mention equivalence and connection that implies a transformation consistent with isometry.

Therefore, the best answer would be the second option with the equivalent triangles.
