Figure 10
Figure 10 shows part of a machine made of eight identical metal spheres (balls)
welded together in
a square formation.
Each sphere has a 2 cm radius.
(a)
The eight spheres in Figure 10 fit exactly into a box (see Figure 11).

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
