Understanding Transformations: Translation of Quadrilaterals

The video tutorial explains how Alicia translates quadrilateral PQRS by moving it four units to the left and three units up to create quadrilateral A'B'C'D'. It describes how to write a rule for this transformation, focusing on the changes in X and Y coordinates. The tutorial emphasizes that a simple translation involves shifting the X coordinate by subtracting four and the Y coordinate by adding three.

What is the initial task described in the video regarding quadrilateral PQRS?

• To reflect it over the Y-axis

• To rotate it 90 degrees

• To translate it to form quadrilateral A'B'C'D'

• To scale it by a factor of 2

What does a transformation rule generally describe?

• The color change of a shape

• The mapping of original coordinates to new coordinates

• The size increase of a shape

• The rotation angle of a shape

In a simple translation, how are the new coordinates determined?

• By reflecting the original coordinates

• By scaling the original coordinates

• By shifting the original coordinates

• By rotating the original coordinates

How does moving four units to the left affect the X-coordinate?

• It adds four to the X-coordinate

• It subtracts four from the X-coordinate

• It divides the X-coordinate by four

• It doubles the X-coordinate

What is the effect of moving three units up on the Y-coordinate?

• It subtracts three from the Y-coordinate

• It divides the Y-coordinate by three

• It adds three to the Y-coordinate

• It doubles the Y-coordinate

What is the final rule for the transformation of quadrilateral PQRS?

• X-3, Y+4

• X+4, Y-3

• X+3, Y-4

• X-4, Y+3

Which of the following is NOT a part of the transformation process described?

• Changing the shape's color

• Mapping to new coordinates

• Shifting Y-coordinate

• Shifting X-coordinate
