2-115.

For part (b) of problem 2-114, explain how to show the triangles are congruent using a sequence of rigid transformations.

What two transformations do you need to do to make the left side
line up exactly on top of the right side?

Start by rotating the triangle $180^\circ$.

After rotating the triangle what is the last transformation needed to align the triangles?
