Question

11. To describe a sequence of transformations that maps triangle ABC onto triangle A"B"C", a student starts with a reflection over the x-axis. How should the student complete the sequence of transformations to map triangle ABC to triangle A"B"C"?

Answer 1

To describe a sequence of transformations that maps triangle ABC onto triangle A"B"C", a student starts with a reflection over the x-axis. The student student complete the sequence of transformations to map triangle ABC to triangle A"B"C" is by translating the figure 2 units to the right. Translate the figure 6 units up.

Answer 2

Answer:

Step-by-step explanation:

Preston says the sequence of transformations that maps triangle ABC onto triangle DEF is: rotate it 180 degrees about the origin, and then translate it up 7 units.

Chanel says the sequence of transformations that maps triangle ABC onto triangle DEF is: reflect it across the x-axis, then reflect it across the y-axis, and then translate it up 6 units and left 1 unit.

Part A

First, take a look at Preston’s sequence. How does a 180-degree rotation about the origin change the coordinates of a shape?
