Identify Transformations

Define translation in geometry.

• A transformation that rotates a shape around a point.

• A transformation that moves a shape a certain distance in a specified direction without changing its size or orientation.

• A transformation that reflects a shape over a line.

• A transformation that scales a shape up or down.

Define rotation in geometry.

• Rotation is a transformation that turns a shape around a fixed point, known as the center of rotation, by a certain angle.

• Rotation is a transformation that enlarges a shape while keeping its center fixed.

• Rotation is a transformation that flips a shape over a line, creating a mirror image.

• Rotation is a transformation that translates a shape to a different location without changing its orientation.

What is the difference between a rotation and a reflection?

• A rotation flips a shape over a line, while a reflection turns a shape around a point.

• A rotation turns a shape around a point, while a reflection flips a shape over a line.

• A rotation and a reflection are the same thing.

• A rotation changes the size of a shape, while a reflection does not.

What is a transformation in geometry?

• A transformation is an operation that moves or changes a shape in some way to produce a new shape.

• A transformation is a method to calculate the area of a shape.

• A transformation is a technique used to measure angles in geometry.

What are the three main types of transformations?

• Translation (slide), rotation (turn), and reflection (flip)

• Dilation (enlarge), compression (shrink), and translation (slide)

• Rotation (turn), scaling (resize), and reflection (flip)

• Translation (slide), rotation (turn), and distortion (warp)

What is a rotation of 180 degrees?

• A rotation of 180 degrees turns a shape around a point to face the opposite direction.

• A rotation of 180 degrees flips a shape upside down without changing its orientation.

• A rotation of 180 degrees moves a shape to the right by 180 units.

• A rotation of 180 degrees turns a shape around a point to face the same direction.

Define reflection in geometry.

• Reflection is a transformation that flips a shape over a line, creating a mirror image of the original shape.

• Reflection is a process of rotating a shape around a point.

• Reflection is a transformation that enlarges a shape while maintaining its proportions.

• Reflection is a method of translating a shape to a different location.

What is the effect of reflecting a shape over the x-axis?

• It changes the sign of the x-coordinates of the points of the shape.

• It changes the sign of the y-coordinates of the points of the shape.

• It rotates the shape 180 degrees around the origin.

• It translates the shape vertically by a certain distance.

What happens when you translate a shape 4 units to the right?

• Translating a shape 4 units to the right adds 4 to the x-coordinates of all points of the shape.

• Translating a shape 4 units to the right adds 4 to the y-coordinates of all points of the shape.

• Translating a shape 4 units to the right moves the shape 4 units up.

• Translating a shape 4 units to the right does not change the shape at all.
