The transformation of right triangle ABC involves two sequential operations: reflection over line AB and a subsequent 90° counterclockwise rotation around point B.
After reflecting over line AB, the image of triangle ABC is formed as a mirror image across the line AB. Following this reflection, a 90° counterclockwise rotation around point B is applied, causing the triangle to reorient itself.
The final configuration, post-rotation, showcases triangle ABC in a new position with respect to its original placement. These transformations illustrate fundamental principles in geometry, offering insights into the effects of reflection and rotation on geometric shapes.
