What are the properties of reflections and rotations and translations?
the image that is reflected is counterclockwise to the original
Which transformation does not produce a congruent image?
A transformation that does not produce a congruent image is a dilation. While dilations change the size of a figure, they maintain the shape, meaning the resulting image is similar but not congruent to the original. In contrast, transformations such as translations, rotations, and reflections preserve both size and shape, resulting in congruent images.
What term describes a transformation that does not change a figure's size or shape?
The term that describes a transformation that does not change a figure's size or shape is "isometry." Isometric transformations include translations, rotations, and reflections, which maintain the original dimensions and angles of the figure. As a result, the pre-image and image of the transformation are congruent.
How are coordinates of the image related to the coordinates of the preimage?
The coordinates of the image are typically related to the coordinates of the preimage through a specific transformation, which can include translations, rotations, reflections, or dilations. For example, if a transformation is defined by a function or a matrix, the coordinates of the image can be calculated by applying that function or matrix to the coordinates of the preimage. Thus, the relationship depends on the nature of the transformation applied.
What is a rigid motion?
A rigid motion is a transformation in geometry that preserves the shape and size of a figure. This means that distances between points and angles remain unchanged during the transformation. Common types of rigid motions include translations, rotations, and reflections. Since the original figure and its transformed image are congruent, rigid motions do not alter the overall structure of the figure.

Which transformation does not always result in an image that is congruent to the original figure?
A dilation (or scaling) is a transformation that does not always result in an image that is congruent to the original figure. While translations, rotations, and reflections always produce congruent figures, dilations change the size of the figure, which means the image may be similar to, but not congruent with, the original figure.

What is rigid motion?
Rigid motion refers to a transformation of a geometric figure that preserves distances and angles, meaning the shape and size of the figure remain unchanged. Common types of rigid motions include translations (sliding), rotations (turning), and reflections (flipping). In essence, during a rigid motion, the pre-image and its image are congruent. This concept is fundamental in geometry, as it helps in understanding symmetries and maintaining the integrity of shapes during transformations.
Is it possible to perform two reflections of an object so that the final image is identical to the original image?
No, it is not possible to perform two reflections of an object that result in the final image being identical to the original image, unless the object is already symmetrical. Reflections change the orientation of the object, so multiple reflections will create a different image.
What is ghosting in photography and how does it affect the quality of an image?
Ghosting in photography refers to a phenomenon where unwanted reflections or artifacts appear in an image due to light bouncing off the lens elements or filters. This can result in reduced contrast, clarity, and overall image quality.
What does a polarizer do and how does it affect the quality of the image?
A polarizer is a filter that reduces glare and reflections in photos by blocking certain light waves. It can enhance colors, increase contrast, and improve overall image quality by reducing unwanted light.
Which polygons in the diagram are images of polygon ABCD under similarity transformations?
To determine which polygons in the diagram are images of polygon ABCD under similarity transformations, look for shapes that maintain the same angles and have proportional side lengths compared to ABCD. Similarity transformations include translations, rotations, reflections, and dilations. Any polygon that matches these criteria will be a valid image of ABCD. Without the specific diagram, I cannot identify the exact polygons, but those that have these properties are the images.
What is a reflection tesselation?
A reflection tessellation is a type of tessellation created by reflecting a shape across a line, producing a pattern that covers a plane without any gaps or overlaps. This process involves taking a basic geometric shape, such as a polygon, and generating its mirror image to form a repeating design. Reflection tessellations can create intricate and visually appealing patterns, often found in art and architecture. They are a subset of more general tessellations, which can also include translations, rotations, and glide reflections.
