A rotation is when you do this to a figure.
What is spin/turn it?
What is (x,y) called?
Coordinate Point
These are the three properties under transformations.
What are translations, reflections, rotations
Find the new coordinates of (10,12) if you translate the point three units left and 4 units up.
What is (7,16)?
What is the difference between a Translation and Rotation?
Rotation-Turn
Translation-move/slide
What type of transformation would you see the following rule (x+3,y-2)
Translation
What does congruent meant
Same shape, same size
Write the notation of point (x,y) after it moves 3 spots to the left and 7 spots up.
What is (x-3,y+7)?
True or false. I can rotate a figure to the position of a reflection
true
What is the rule if you have a rotation across the x-axis?
The x-coordinate stays the same, the y-coordinate is the opposite sign
A picture with one point (-3,4) was reflected over the line y-axis . What should be the new coordinates of the point?
What is (3,4)?
True or false. Rotations have one rule
false
(x-2,y+7) B(0,-1)Given the rule and coordinate point identify B'
(-2,6)
These properties are preserved under a translation, reflection, and rotation
Congruency
Describe the reflection D(5,5) D'(5,-5)
Reflection across the x-axis
Triangle ∆JKL is rotated clockwise about the origin, if the triangle has an original position in Quadrant II, what Quadrant will it move to next?
Quadrant I
Graph ∆DEF after a reflection across the y-axis D(2,8) E(2,2) F(6,2)
What is D'(-2,8), E'(-2,2), F'(-6,2)?
This property SOMETIMES changes under a rotation.
What is location
