What are congruence transformations?
Congruence transformations, also known as rigid transformations, are operations that alter the position or orientation of a shape without changing its size or shape. The primary types of congruence transformations include translations (sliding), rotations (turning), and reflections (flipping). These transformations preserve distances and angles, meaning the original and transformed shapes remain congruent. As a result, congruence transformations are fundamental in geometry for analyzing the properties of figures.
Which transformation does not always result in congruent figures in the coordinate plane?
A transformation that does not always result in congruent figures in the coordinate plane is dilation. While dilations can resize figures, they change the dimensions of the original shape, leading to figures that are similar but not congruent. In contrast, transformations like translations, rotations, and reflections preserve the size and shape of the figures, resulting in congruence.
How do translations reflections and rotations affect the size and shape of an image?
None of these transformations affect the size nor shape of the image.
What transformation is not a congruent image?
A transformation that is not a congruent image is a dilation. Unlike rigid transformations such as translations, rotations, and reflections that preserve shape and size, dilation changes the size of a figure while maintaining its shape. This means that the original figure and the dilated figure are similar, but not congruent, as their dimensions differ.
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.
Why are isometric transformation a part of the similarity transformations?
Isometric transformations are a subset of similarity transformations because they preserve both shape and size, meaning that the distances between points remain unchanged. Similarity transformations, which include isometric transformations, preserve the shape but can also allow for changes in size through scaling. However, isometric transformations specifically maintain the original dimensions of geometric figures, ensuring that angles and relative proportions are conserved. Thus, while all isometric transformations are similarity transformations, not all similarity transformations are isometric.
Can the isometric transformation change size?
No, isometric transformations do not change the size of shapes. They preserve distances and angles, meaning that the original shape and its image after the transformation will have the same dimensions. Examples of isometric transformations include translations, rotations, and reflections, which maintain the object's size and shape.

How transformations are different?
Transformations are different by their size but same shape the only thing that change is their coordinates and size.

What does congruence transformations mean?
These are transformations that do not change the shape or size, only its location (translation) or orientation (rotation).

In contrast, transformations such as translations, rotations, and reflections preserve both size and shape, resulting in congruent images.
What transformations preserves the measures of the angles but changes the lengths of the sides of the figure?
The transformations that preserve the measures of the angles but change the lengths of the sides of a figure are known as similarity transformations. These include dilation, where a figure is enlarged or reduced proportionally, and certain types of non-rigid transformations. Unlike rigid transformations (like translations, rotations, and reflections), which maintain both angle measures and side lengths, similarity transformations allow for changes in size while keeping the shape intact.
