Rigid Transformations

Front

Describe the transformation shown in the graph: Rotate 90 degrees CCW.

Back

A rotation is a transformation that turns a figure around a fixed point, in this case, 90 degrees counterclockwise.

Front

When you translate (x-4,y), the point will move _____?

Back

4 units left.

Front

When you translate (x,y+6), the point will move _____?

Back

6 units up.

Front

Find the image of A( -3, 5) after translating (x,y) --> (x , y-4) then reflecting across the y-axis: What is the image?

Back

(3,1).

Front

What is a translation in geometry?

Back

A translation is a transformation that moves every point of a figure the same distance in the same direction.

Front

What is a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

What is a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point by a certain angle.

Front

What does it mean for a transformation to be rigid?

Back

A rigid transformation preserves the shape and size of a figure.

Front

What is the effect of reflecting a point across the y-axis?

Back

The x-coordinate of the point changes sign, while the y-coordinate remains the same.
