# What are the similarities between reflection and rotation?

## What are the similarities between reflection and rotation?

Comparing rotation and reflection ~ They are both on a coordinate plane. ~ You can rotate and reflect the same shape. ~ Size remains constant in reflection and rotation. ~they can both be in different quadrants.

### What do translation rotation and reflection have in common?

Translation is when we slide a figure in any direction. Reflection is when we flip a figure over a line. Rotation is when we rotate a figure a certain degree around a point. Dilation is when we enlarge or reduce a figure.

#### What are some similarities between translations and reflections?

Reflection and translation both are rigid motions and thus create congruent images ( Rigid motion creates congruent images ) such that the shape and size doesn’t change.

What are the similarities and differences between translation rotation and reflection?

Translation moves the object without rotating it or changing its size. Reflection flips the object about a line of reflection. Rotation rotates a figure about a fixed point. Dilation changes the size of a figure without changing its essential shape.

What is rotation and reflection?

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.

## Is rotation same as reflection?

A reflection is the flipping of a point or figure over a line of reflection (the mirror line). A rotation is the turning of a figure or object around a fixed point.

### What is rotation translation reflection?

key idea. A reflection flips the figure over a line to create a mirror image. A rotation turns the figure around a point. A translation slides the figure to a different location.

#### Is rotation congruent or similar?

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.

How do you do similarities?

If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.

What is an example of similarity?

The definition of a similarity is a quality or state of having something in common. When you and your cousin look exactly alike, this is an example of when the similarity between you two is striking.

## How is a rotation different from a reflection?

### What is the difference between reflection, rotation and translation?

Transformation means movement of objects in the coordinate plane. Transformation can be done in a number of ways, including reflection, rotation, and translation. 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.

#### When do you use a similarity transformation in geometry?

Our example may sound a bit silly, but in geometry we use transformations all the time to bring two objects near each other, turn them to face the same way, and, if necessary, flip them to see if they are similar. What is Similarity? Two geometric shapes are similar if they have the same shape but are different in size.

Why are the coordinates of reflection and rotation important?

~ The coordinates allow us to easily describe the image and its pre-image. ~ a negative angle of rotation turns the figure in a clockwise direction. ~ They are both on a coordinate plane. ~ You can rotate and reflect the same shape. ~ Size remains constant in reflection and rotation. ~they can both be in different quadrants.

Which is an example of the rotation of an object?

Rotation is rotating an object about a fixed point without changing its size or shape. In some cases, the shapes are rotated just a few degrees, while in other cases, they may be rotated significantly. In this example, the alphabet is rotated-clockwise.
