Front

Describe the Transformation: A rotation is also called a ___________.

Back

Rotation

Front

Point (-5,2) is reflected over the y axis. Where is the new point located?

Back

(5,2)

Front

A slide is also called a _________.

Back

Translation

Front

A turn is also called a ___________.

Back

Rotation

Front

Write a rule for the translation: (x +2, y - 1) is a translation that moves a point how?

Back

It moves the point 2 units to the right and 1 unit down.

Front

What is the effect of a reflection over the x-axis on the point (a,b)?

Back

The new point will be (a,-b).

Front

What is the effect of a translation on the point (x,y) by the vector (3, -4)?

Back

The new point will be (x+3, y-4).

Front

What is the definition of a geometric transformation?

Back

A geometric transformation is a function that maps a set of points to another set of points, altering their position, size, or orientation.

Front

What is the difference between a rotation and a reflection?

Back

A rotation turns a figure around a fixed point, while a reflection flips a figure over a line.

Front

If a point (x,y) is rotated 90 degrees counterclockwise around the origin, what is the new position?

Back

The new position will be (-y, x).
