Math Problem Statement

Which transformation would take Figure A to Figure B?

Solution

To determine the transformation that takes Figure A to Figure B, let's analyze the figures closely.

  1. Reflection: Figure B appears to be a mirror image of Figure A across the y-axis. This suggests that a reflection over the y-axis is involved in the transformation.

    Here's the reasoning:

    • Figure A is located in the third quadrant (negative x and y coordinates), while Figure B is located in the second quadrant (positive y, but negative x).
    • The orientation of the shape in Figure B is consistent with a reflection. The left-right orientation has been flipped, while the size and shape remain unchanged.

Therefore, the transformation is a reflection over the y-axis.

Here are 5 related questions to consider:

  1. How can we express a reflection over the x-axis mathematically?
  2. What would happen if we rotated Figure A 90 degrees clockwise? Where would it be?
  3. Could a translation alone move Figure A to the position of Figure B?
  4. How do we combine multiple transformations (e.g., reflection and rotation) in a single transformation?
  5. What would be the result of a reflection across both the x-axis and y-axis?

Tip: When identifying transformations, always consider whether the shape's orientation, size, and position change—this can help determine the type of transformation (reflection, rotation, translation, etc.).
