What information, besides the coordinates of the object, is needed to draw a reflected figure in the coordinate plane?

Answer 1

To draw a reflected figure in the coordinate plane, in addition to the coordinates of the object, you need the following information:

1. Line of Reflection: You need to know the specific line across which the figure is to be reflected. This could be one of the axes (like the x-axis or y-axis), or it could be any other line, which may be defined by an equation (e.g., \(y = mx + b\)) or specific points.

2. Orientation: Depending on what the reflection is across (for example, reflecting over a vertical line vs. a horizontal line), you may need to understand how the orientation of the figure will change after reflection.

3. Properties of the Figure: Knowing any special characteristics of the figure (like being symmetrical, types of angles, lengths of sides, etc.) may assist in accurately reflecting the figure.

With these pieces of information, you can perform the reflection accurately on the coordinate plane.
