Combined Transformations

The video tutorial explains mathematical transformations on a coordinate plane, including dilation, translation, reflection, and rotation. It emphasizes the importance of the preimage and image, and the significance of the order in which transformations are applied. Examples demonstrate how to combine transformations effectively. The tutorial concludes with applications of transformations in fields like engineering and video game design.

What is the term used for the original shape before any transformation?

• Image

• Preimage

• Reflection

• Rotation

Which transformation involves resizing a shape?

• Translation

• Rotation

• Reflection

• Dilation

How does translation affect a shape on a coordinate plane?

• It mirrors the shape.

• It resizes the shape.

• It rotates the shape.

• It slides the shape to a new location.

What happens to a shape when it is reflected over the x-axis?

• It is rotated 90 degrees.

• It is translated horizontally.

• It is mirrored over the x-axis.

• It is resized.

Which point is commonly used as the center for rotation?

• The x-axis

• The origin

• The y-axis

• The midpoint of the shape

Why is the order of transformations important?

• It determines the final size of the shape.

• It affects the final position and orientation of the shape.

• It changes the type of transformation applied.

• It alters the color of the shape.

In the example of combining transformations, what is the first step when rotating a rectangle 270 degrees?

• Dilate the rectangle

• Translate the rectangle

• Reflect the rectangle

• Rotate the rectangle
