Math Problem Statement

Determine a series of transformations that would map Figure I onto Figure J.

Solution

To determine the series of transformations that map Figure II onto Figure JJ, we need to carefully analyze the positions and orientations of the two figures.

Step-by-Step Process:

  1. Reflection across the x-axis:

    • Figure JJ appears to be an upside-down version of Figure II, so a reflection over the x-axis would map the shape from above the x-axis (where Figure II is) to below it (where Figure JJ is).
  2. Translation:

    • After reflecting Figure II over the x-axis, we can see that Figure JJ is shifted downward and to the right. This suggests a translation is needed.
    • Translation can be calculated by looking at the movement of a specific point from Figure II to Figure JJ.
      • For example, if we consider a point on Figure II, such as (1,6)(-1, 6), after reflecting over the x-axis, it will be at (1,6)(-1, -6). We then need to translate it to its corresponding point on Figure JJ, which could be something like (1,3)(-1, -3), so this requires a vertical translation upward by 3 units.

Thus, the series of transformations that would map Figure II onto Figure JJ would be:

  1. Reflect Figure II over the x-axis.
  2. Translate the resulting figure downward (or upward) by the necessary amount to align with Figure JJ.

Would you like more details on any of these transformations, or how to calculate them specifically?

Tip:

When analyzing transformations, always break them down into the simplest operations (reflection, rotation, translation) to avoid confusion.
