Question

in the figure shown, which composition of rigid motions will map one triangle onto the other? two translations rotation followed by a translation reflection followed by a translation

Rigid - motions include translations, rotations, and reflections. By observing the orientation and position of the two triangles, first rotating the top - triangle to match the orientation of the bottom - triangle and then translating it to the correct position will map one triangle onto the other.

Answer:

rotation followed by a translation
