In this worksheet, we will practice identifying an image, an object, and a mirror line and applying this knowledge in various situations.
A rectangle is reflected in and a larger rectangle is formed by joining and its reflection. Given that and , find the perimeter of the larger rectangle.
Given that is the image of after a reflection in the line, give the coordinates of , and .
- A is , is , is
- B is , is , is
- C is , is , is
Points and have coordinates and respectively. Given that is the image of after a reflection in the -axis, find the perimeter of .
