Transformation
Show/Hide
Is a change in position, shape, or size of a figure
There are four basic transformations:
Flip (Reflection)
Slide (Translation)
Turn (Rotation)
Dilation
Similar figures
Show/Hide
Figures with same shape.
Reflection
Show/Hide
Is a flip over a mirror line (without changing size)
When a point is reflected over the y- axis, the x- coordinate changes sign.
Translation
Show/Hide
Moving an object in space without changing its size, shape or orientation
Rotation
Show/Hide
Is a turn of a figure around a point. The point can be on or in the figure, or outside the figure.
Rigid Transformation
Show/Hide
Any transformation that does not change the size of the object (rotations, translations and reflections)
Dilation
Show/Hide
A transformation that grows or shrinks a polygon by a given proportion
