## How do you describe a transformation in geometry?

A translation moves a shape up, down or from side to side but it does not change its appearance in any other way. A transformation is a way of changing the size or position of a shape. … Every point in the shape is translated the same distance in the same direction.

## Which transformation makes congruent?

Rotations, reflections, and translations are isometric. That means that these transformations do not change the size of the figure. If the size and shape of the figure is not changed, then the figures are congruent.

## What describes a transformation?

A transformation changes the size, shape, or position of a figure and creates a new figure. A geometry transformation is either rigid or non-rigid; another word for a rigid transformation is “isometry”. An isometry, such as a rotation, translation, or reflection, does not change the size or shape of the figure.

## What is an example of a congruent shape?

Congruent shapes can be said as identical shapes in terms of sides and angles. Two bricks and two playing dice are always congruent to each other.

## How do you identify transformations?

The function translation / transformation rules:

1. f (x) + b shifts the function b units upward.
2. f (x) – b shifts the function b units downward.
3. f (x + b) shifts the function b units to the left.
4. f (x – b) shifts the function b units to the right.
5. –f (x) reflects the function in the x-axis (that is, upside-down).

## What do you know about transformations?

A transformation is a process that manipulates a polygon or other two-dimensional object on a plane or coordinate system. Mathematical transformations describe how two-dimensional figures move around a plane or coordinate system. A preimage or inverse image is the two-dimensional shape before any transformation.

## What are the different types of transformations in geometry?

The four main types of transformations are translations, reflections, rotations, and scaling.

• Translations. A translation moves every point by a fixed distance in the same direction. …
• Reflections. …
• Rotations. …
• Scaling. …
• Vertical Translations. …
• Horizontal Translations. …
• Reflections. …
• Learning Objectives.

## How do you identify congruent figures?

Two polygons are congruent if they are the same size and shape – that is, if their corresponding angles and sides are equal. Move your mouse cursor over the parts of each figure on the left to see the corresponding parts of the congruent figure on the right.

## What do congruent figures look like?

If two figures are congruent, then they’re exactly the same shape, and they’re exactly the same size. They may appear different because one is shifted or rotated a certain way, but they’re still the same shape, and all the sides of one are the same length as the corresponding sides of the other.
