The first way:
Reflect the figure I across the x-axis.
Translate the figure I and its reflection and rotate them 90 degrees.
The second way:
Reflect the figure I across the x-axis.
Rotate 90 degrees counterclockwise.
Rotate it across the y-axis.
To create a square design using a shaded triangle, you can reflect it across the x-axis, translate, and rotate it for one method. In a second method, you can reflect the triangle, rotate it 90 degrees counterclockwise, and then reflect it across the y-axis. Both methods use transformations to achieve the desired design symmetry.
