Geometric Transformations

Terms in this set (19)

In the direction to the way in which the hands of a clock move around. Moving from right to left in a circular motion.
Clockwise
In the opposite direction to the way in which the hands of a clock move around. Moving from left to right in a circular motion.
Counterclockwise
This word is a synonym for rigid transformation and literally means "equal measure".
Isometry
A line which cuts a line segment into two equal parts at 90°.
Perpendicular Bisector
A line that divides an object into two equal halves, thereby creating a mirror like reflection of either side of the object.
Axis of Symmetry
These transformations maintain the size and shape of the preimage.
Rigid Transformations
These transformations do not maintain the size and shape of the preimage.
Nonrigid Transformations
This word refers to the arrangement of points, relative to one another, after a transformation has occurred.
Orientation
The original appearance of a figure in a transformation operation.
Pre-image
The final appearance of a figure after a transformation operation.
Image
Connecting the preimage points to their corresponding image points after this transformation has occurred will always result in congruent and parallel line segments.
Translation
Connecting the preimage points to the center of this transformation to their corresponding image points always results in the angle of this transformation being formed.
Rotation
For this transformation, the axis of symmetry is always the perpendicular bisector of the line segments connecting preimage points to their corresponding image points.
Reflection
The line segments joining preimage points to their corresponding image points always pass through the center of this transformation.
Dilation
What transformation can never have any fixed points?
