Translations Flashcards
Rotation
Transformation about a point called the center of rotation. Each point and its image are same distance from center of rotation
When reflecting across the x-axis what has to change?
Y
(x,y) → (x,-y)
Equation for 180 degree CW rotation
(x,y)→(-x,-y)
whats another word for rotation
turn
For a reflection across the y axis, what needs to be negative?
x
(x,y) →(-x,y)
Whats another word for a translation
slide
Whats the vertical translation equation
(x,y)→ (x,y+/- h)
h being any number
Equation for reflection across the y=x line
(x,y)→(y,x)
coordinates flip/switch
whats another word for reflection
flip
What is compositional translation?
When both x and y changes
What has to change in a vertical translation
The ‘y’
(x,y) → (x, y+2)
Whats the equation for a 90 degree clockwise rotation
(x,y)→(y,-x)
Reflection
Transformation across a line, each point and its image are the same distance from the line of reflection
What translatiom is this?
(x,y)→ (x-3,y)
Horozontal translation
Translation
Transformation in which all points of a figure move the same distance in the same direction
