Question

which sequence of transformations maps triangle abc onto triangle abc? 1 point

Explanation:

Step1: Observe the orientation change

We can see that triangle ABC needs to be rotated 180 degrees about the origin to change its orientation to match triangle A'B'C'. The rule for a 180 - degree rotation about the origin is $(x,y)\to(-x,-y)$.

Step2: Check for translation

After rotation, no further translation is needed as the vertices of the rotated triangle will match the vertices of triangle A'B'C'.

Answer:

A 180 - degree rotation about the origin.
