Question

the triangles shown are congruent by the sss congruence theorem. the diagram shows the sequence of three rigid transformations used to map △abc onto △a″b″c″. what is the sequence of the transformations? rotation, then translation, then reflection translation, then rotation, then reflection rotation, then reflection, then translation translation, then reflection, then rotation

Explanation:

First, observe the general movement of the triangle. A translation moves the triangle to a general position - like moving it from one place to another without changing its orientation. Then, a rotation changes its orientation around a point. Finally, a reflection flips it over a line to match the final - mapped triangle.

Answer:

translation, then rotation, then reflection
