## Does order matter in geometric transformations?

**The order does not matter**. Algebraically we have y=12f(x3). Of our four transformations, (1) and (3) are in the x direction while (2) and (4) are in the y direction. The order matters whenever we combine a stretch and a translation in the same direction.

## What are the rules for transformations in geometry?

**Terms in this set (10)**

- rule for 90° rotation counterclockwise. (x,y)->(-y,x)
- rule for 180° rotation. …
- rule for 270° rotation. …
- rule for 360° rotation. …
- rule for reflection across the line y=x. …
- rule for reflection across the line y=-x. …
- rule for translation a units to the right. …
- rule for translation a units to the left.

## Does order matter in rigid transformations?

With a rigid transformation, figures like polygons have corresponding sides of the same length and corresponding angles of the same measure. … There are many ways to show that 2 figures are congruent since many sequences of transformations take a figure to the same image. However, **order matters in a set of instructions**.

## Does order of rotation and translation matter?

In a composite transformation, **the order of the individual transformations is important**. For example, if you first rotate, then scale, then translate, you get a different result than if you first translate, then rotate, then scale.

## Does order matter in similarity transformation?

Possible answer: **The transformations occur sequentially, and order matters**. The result may be the same as a single transformation.

## What is the importance of sequence of transformation?

In a composite transformation, the order of individual transformations is important. For example, if you first **rotate**, then scale, then translate, you get a different result than if you first translate, then rotate, then scale. In GDI+, composite transformations are built from left to right.

## Which sequence of transformations produces a congruent figure?

The transformations that always produce congruent figures are **TRANSLATIONS, REFLECTIONS, and ROTATIONS**.

## How can the transformation be amended such that the translation can occur before the reflection and have the image remain in the same position?

How can the transformation be amended such that the translation can occur before the reflection and have the image remain in the same position? **Translate the pre-image down 4 and right 3 and then reflect the figure over the x-axis.**

## What are the rules for translations rotations and reflections?

Reflection is flipping an object across a line without changing its size or shape. Rotation is rotating an object about a fixed point without changing its size or shape. **Translation is sliding a** figure in any direction without changing its size, shape or orientation.

## What are the coordinate rules for translations?

**Coordinate plane rules:**

- Over the x-axis: (x, y) → (x, –y)
- Over the y-axis: (x, y) → (–x, y)
- Over the line y = x: (x, y) → (y, x)
- Through the origin: (x, y) → (–x, –y)

## Does the order that you perform the transformations change the image in a composition?

A **composite transformation** is when two or more transformations are performed on a figure (called the preimage) to produce a new figure (called the image). … Therefore, the order is important when performing a composite transformation.

## Which sequence of transformations will result in similar but not congruent figures?

The correct answer is: **dilation and rotation**.

## What transformation preserves angle measures but not segment lengths?

When a transformation doesn’t change the side lengths and angle measurements of a shape, we call this preserving length and angle measurement. These are **rigid transformations**. Translations, rotations, and reflections are all rigid transformations.
