Vocabulary
Operations that alter the form of a figure. Examples: translations, reflections, dilations, and rotations.
What are transformations?
A translation does what do an image?
A reflection does this to an image.
What is mirror or reflect?
A rotation does this to an image.
What is spin or rotate?
The center, or start, of a coordinate plane is called this.
What is the origin?
A transformation in which a figure is picked up and moved to another location without any change in size or orientation.
What is translation?
Translations can move in these four directions.
What is up, down, left, or right?
A reflection over this axis displays the reflection as if it were a puddle in the ground.
What is the horizontal or x-axis?
This direction of rotation is moving in the same direction as hands on a clock.
What is clockwise?
A quadrant that has all positive x and y values for point coordinates.
What is Quadrant I?
A transformation in which a figure turns around a fixed center point.
What is rotation?
An image starting in quadrant I translated down and to the left, across the origin, ends up in this quadrant.
What is Quadrant III?
A reflection over this axis displays the image as if it were looking in a mirror on a wall.
What is a reflection over the vertical or y-axis?
This direction of rotation moves opposite of the hands on a clock.
What is counter-clockwise?
A quadrant that has all negative x & y values for point coordinates.
What is Quadrant III?
A transformation in which a figure is mirrored over an axis.
What is reflection?
An image in Quadrant I moving in the negative direction on the x-axis will end up in this quadrant.
What is Quadrant II?
A reflection from Quadrant II over the x-axis moves the image to this quadrant.
What is Quadrant III
A quadrant that has positive x values but also contains negative y values for point coordinates.
What is Quadrant IV?
The transformation that is a combination of a reflection, rotation and two translations.
What is a transformation sequence?
An image in Quadrant IV is moving in the positive direction on the x-axis, it ends up in this quadrant.
What is Quadrant IV?
A figure in Quadrant III is reflected over the y-axis, it is moved to this quadrant.
What is Quadrant IV?
The rotation that creates the same image as a rotation 270 degrees clockwise.
What is a rotation 90 degrees counterclockwise?
A quadrant that has negative x values with positive y values for point coordinates.
What is Quadrant II?
