Math Problem Statement

Which transformation would take Figure A to Figure B?

Solution

The question asks about the transformation that would map Figure A to Figure B, shown on a coordinate plane. Looking at the two figures, Figure A is in the fourth quadrant, while Figure B is in the second quadrant. Furthermore, Figure B appears to be rotated counterclockwise compared to Figure A.

To analyze the transformation:

  1. Rotation: The figures seem related by rotation, not reflection. Specifically, a clockwise rotation by 270° around the origin would map Figure A to Figure B. This can be confirmed by observing the orientation of the shapes.

Let's review the given options:

  • Reflection over the line y=xy = -x: This would not map Figure A to Figure B, as reflections over this line would change both the position and orientation differently.
  • Reflection over the line y=xy = x: Similar to the previous reflection, this would not match the transformation.
  • Clockwise rotation of 270° about the origin: This appears to be the correct transformation.
  • Clockwise rotation of 180° about the origin: This would place Figure A in the opposite quadrant (third quadrant), so it is not correct.

Answer: The transformation that takes Figure A to Figure B is a clockwise rotation of 270° about the origin.

Would you like further details on this rotation or any other part of the problem?

Here are five related questions to consider:

  1. How do rotations around the origin differ for different angles (90°, 180°, 270°)?
  2. What is the effect of reflecting a shape over the line y=xy = -x?
  3. How can we calculate the coordinates of points after a 270° clockwise rotation?
  4. Why is the clockwise direction significant in transformations?
  5. How would a reflection differ from a rotation in terms of mapping figures?

Tip: Always check both the quadrant and orientation of the figures when determining the type of transformation.
