# translation and rotation

The vertices of ΔABC are A(-1,1), B(0,3), and C(3,4).

Translation : (x,y) → (x -3, y-3)

Reflection: in the line y = x

Is the composition a glide reflection?  yes or no

Is the image the same if the order of the transformations is switched? (reflection, then glide)     yes or no

-----------------------------------------------------------------------------

using the above verticies....

Rotation:  90 degrees counterclockwise about the orgin

Reflection:  in the y-axis

If the transformations were performed in reverse order (reflection, then rotation), would the final image be the same?   yes or no

Would the reflection of ΔABC in the line y = x produced the same final image?  yes or no

thank you.
