You can use this tool to help you with a reflection.
What is a mirra?
100
A transformation that reflects a figure over a line.
What is a reflection?
100
The point of intersection of the x-axis and y-axis. The point (0,0).
What is the origin?
200
All points move the same __________ and the same __________
What is direction and distance?
200
We need these tools to complete a rotation.
What is a bullseye and a protractor?
200
This changes ONLY with this type of transformation
What is orientation?
200
A transformation that slides a figure along a straight line.
What is a translation?
200
A line that cuts a line segment into equal parts at 90 degrees.
What is a perpendicular bisector?
300
(4 <-, 1↑) means this.
What is left 4, up 1?
300
These are the steps to to find a fixed point.
What is connect corresponding vertices and determine where the perpendicular bisectors meet?
300
This is a reason that a point will not move when undergoing a reflection.
What is on the mirror plane?
300
A transformation that rotates a figure around a fixed point.
What is a rotation?
300
You use this tool to find equal distances away from a fixed point that a point is.
What is a bullseye (or compass)
400
The orientation of a shape does this in a translation
What is stays the same?
400
DAILY DOUBLE (Everyone Plays)
Rotate the given shape 90 degrees about the fixed point!
Teams who have team members talking will not be allowed to respond.
Ms. Bocking will check answers
Any team that gets it right gets 400 points
400
In the worksheet that we did as an extra activity, what did the resulting picture spell?
What is IMAGE?
400
Mapping of one geometrical figure to another according to some rule.
What is a transformation?
400
These lines will never meet.
What is a parallel line?
500
The lines that join corresponding vertices have these two properties.
What is parallel and same length?
500
This measurement of rotation will place the shape back in the same place that is started.
What is 360 degrees?
500
If a triangle was named ABC and was positioned to the right of a mirror, this would be the name of the reflected image.
See Drawing
What is A'C'B'?
500
We didn't cover this type of transformation in class. But it is a transformation that enlarges or reduces a figure by a scale factor. (Look at your definitions in your graphic organizer)
What is a dilation?
500
This is the city in China that Ms. Bocking will be teaching in.
