What is a translation?
100
Rigid motions, such as translations, reflections and rotations, all produce images that are _____________ to their pre-image.
What is congruent?
100
This is the general term that is used to refer to any translation, reflection, rotation or dilation.
What is transformation?
200
What is a reflection or rotations?
200
What do you need to draw to find the point of rotation (Point P).
What are the perpendicular bisectors?
200
Identify the transformation shown below.
What is a reflection?
200
Similar figures can always be mapped onto each other by a composition of _____________ motions.
What is non-rigid?
200
In a translation, the vectors that map points on the pre-image to their corresponding points on the image are all ________________ to each other.
What is parallel?
300
A transformation in which a plane figure turns around a fixed center point.
What is a rotation?
300
It's the proper name for the number that quantifies the "size change" when an object is dilated.
What is the scale factor?
300
It's the triangle in the picture below that is a 90 degree counterclockwise rotation of triangle A.
What is triangle D?
300
It's the proper term for a figure that has been transformed.
What is an image?
300
Rotations come in two different varieties. When a plane figure is rotated as shown below, it is said to have been rotated this direction.
What is counter-clockwise?
400
A transformation that produces an image that is the same shape as the pre-image, but is a different size.
What is a dilation?
400
Rotations come in two different varieties. When a plane figure is rotated as shown below, it is said to have been rotated this direction.
What is clockwise?
400
The dilation in the image appears to be by a scale factor of ______________.
What is 2?
400
Non-rigid motions, such as dilations, always produce images that are ________________ to their pre-image, meaning the corresponding angle measures are the same, but the corresponding lengths have been scaled.
What is similar?
400
These transformations are said to be rigid because they all produce images that are congruent to the pre-image.
What are translations, reflections and rotations?
500
The picture below appears to show these two different types of transformations.
What are reflections and a rotation?
500
This transformation is said to be non-rigid because it's the only transformation that produces an image that isn't congruent to the pre-image.
What is dilation?
500
The picture below appears to show a 180 degree rotation, but could also be described as this composition of 2 transformations.
What is a reflection across the x-axis and then the y-axis?
(Or vice versa)
500
Several transformations combined as one is often referred to as a _______________ of transformations.
What is a composition?
500
In the image below, the segments that connect each point with it's image, all share this same relationship to the line of reflection.
What is perpendicular?
