Transformations

What is the line of reflection?

• The line that divides a figure into two equal parts.

• The line over which a figure is flipped in a reflection transformation.

• The line that connects two points in a figure.

• The line that represents the axis of rotation.

How many degrees was the figure rotated? 90 degrees counterclockwise, 180 degrees, 270 counterclockwise.

• 90 degrees counterclockwise

• 180 degrees

• 270 degrees counterclockwise

• 360 degrees

What is a reflection?

• A transformation that rotates a figure around a point.

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

• A transformation that enlarges or reduces a figure in size.

• A transformation that translates a figure to a different location.

What is a translation?

• A translation is a transformation that slides a figure from one position to another without turning it.

• A translation is a rotation of a figure around a point.

• A translation is a reflection of a figure over a line.

• A translation is a scaling of a figure to a different size.

A turn is also called a ___________.

• Rotation

• Revolution

• Twist

• Spin

A slide is also called a _________.

• Translation

• Projection

• Slide Show

• Image

What does it mean to rotate a figure 90 degrees clockwise?

• It means to turn the figure 90 degrees in the direction of the clock hands.

• It means to flip the figure upside down.

• It means to turn the figure 90 degrees in the opposite direction of the clock hands.

• It means to stretch the figure horizontally.

What happens to the coordinates of a point (x,y) during a translation of 5 units right?

• The new coordinates will be (x+5, y).

• The new coordinates will be (x-5, y).

• The new coordinates will be (x, y+5).

• The new coordinates will be (x, y-5).

When you translate, (x-4,y) will move _____.

• 4 units left

• 4 units right

• 4 units up

• 4 units down

What is the difference between rotation and reflection?

• Rotation flips a figure over a line, while reflection turns it around a point.

• Rotation turns a figure around a point, while reflection flips it over a line.

• Rotation and reflection are the same transformations.

• Rotation changes the size of a figure, while reflection does not.
