Transcript of Transformations-Kevin Bond
Moving a shape, without rotating or flipping it. The shape still looks exactly the same.
There is a central point that stays fixed and everything else moves around that point in a circle. A "full rotation" is 360 degrees.
An image or shape as it would be seen in a mirror. A flip over a line.
Transormations--moving a shape so that it is in a different position, but still has the same size, area, angles and line length.
Types of transformations
Examples of Translations
Examples of Rotations
Examples of Reflections
The graph on the left shows an example of a transformation. Which transformation is shown?
reflection in origin
Reflection in origin
If a reflection in the line y =-x occurs, the the rule for this reflection is?
Which transformation turns a figure?
Transformations-same shape, size, and same measurement, BUT different position.
object vs image
Translation=sliding a shape around
sliding-up/down and/or left/right
turn=moving around a point
amount of movement=degrees
MCC9‐12.G.CO.4 Develop definitions of rotations, reflections, and translations in terms of angles, circles,
perpendicular lines, parallel lines, and line segments.
