Review: Coordinate Grid and Transformations

Review Week 2023: Day 1

Coordinate Plane and Transformations

Coordinate Plane

​On a coordinate plane:

• The Y Axis is the center line which goes up and down

• The X Axis is the center line which goes side to side​

Multiple Choice

Which letter represents the first number in an ordered pair?

• x

• y

Multiple Choice

If my coordinates are (3, 4) what is my y?

• 3

• 4

Multiple Choice

How do you correctly write an ordered pair?

• x,y

• y,x

• (x,y)

Multiple Choice

Name the ordered pair for point C.

• (3,4)

• (4,3)

Multiple Choice

Where is Point A on the coordinate plane?

• (7,4)

• (9,3)

• (1,3)

• (4,7)

​Transformations:

Translations and Reflections​

What is a Translation

A rigid motion transformation that moves every point of one figure the same amount and preserves the orientation. 

​

In other word: The shape moves but it does not twist or change.​

What is a Reflection

A type of transformation where every point is mapped across a line. The original point and the new point are equidistant from the line. 

​

In other words: the shape reflects across a line​

Multiple Choice

What is a translation?

• The shape moves but does not change

• The shape flip around

• The shape disappears

Multiple Choice

What is a reflection?

• The shape does not move

• The shape reflects across a line

• The shape grows way bigger

Multiple Choice

Describe the transformation in the image.

• Translation

• Reflection

• Rotation

Multiple Choice

Name the transformation.

• Translation

• Reflection

• Rotation

​Transformations:

Rotations and Dilations​

Multiple Choice

If the dotted figure is the image, the original figure was reflected over the ...

• x-axis

• y-axis

​Let's Review!

​What are rotations

The shape turns around the origin. The shape does not change size. It is like it is on a wheel.​

​

In other word: The shape turns but it does not twist or change.​

What is a DILATION?

A type of transformation where the shape grows by a scale factor.

​

​

In other words: the shape grows or shrinks by a certain amount. across a line​

Multiple Choice

What is a rotation?

• The shape moves but does not change

• The shape flip around

• The shapes turns around the origin (0,0)

Multiple Choice

What is a dilation?

• The shape grows or shrinks by a certain amount

• The shape reflects across a line

• The shape flips all over the place

Multiple Choice

A turn is also called a ___________.

• Translation

• Reflection

• Rotation

• Transformation

Multiple Choice

What is this picture an example of? 

• An angle

• A cat vertex 

• Rotation 

Multiple Choice

What type of transformation is this?

• rotation

• translation

• reflection

• dilation

Multiple Choice

 Describe the Transformation

• Translation

• Rotation

• Reflection
