Rotation
Spinning on an imaginary axis, this takes Earth exactly 24 hours to complete.
What is a rotation
These are the four properties under transformations.
What are shape, size, orientation, and location?
A reflection is when you do this to a figure.
What is flip it or make a mirror image of it?
A dilation is when you do this to a figure.
What is make it bigger or smaller?
Find the new coordinates of (10,12) if you translate the point three units left and 4 units up.
What is (7,16)?
This planet in our solar system has a day shorter than Earth's but takes the longest to orbit the Sun, and spins on its side.
Which transformation does not result in a congruent figure?
What is a dilation?
Find the new coordinates of (3,-2) after you reflect the point over the x-axis.
What is (-3,-2)?
Find the new coordinates of (3,-2) if you dilate the point with a scale factor of 4.
What is (12,-8)?
A translation is when you do this to a figure.
What is move it right, left, up, or down?
When a coordinate point is rotated 90° clockwise, the original (x, y) becomes this.
Response: What is counter-clockwise?
These properties change under a reflection.
What are orientation and location?
Write the notation of point (x,y) after it is reflected over the y-axis.
What is (-x,y)?
Write the notation of point (x,y) after it is dilated with r=6.
What is (6x,6y)?
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)?
If you rotate a coordinate point (-3, 4) by 90° counter-clockwise, the new coordinates become this.
What is (-4, -3)?
These properties are preserved under a dilation.
What are shape and orientation
A picture with one point (-3,4) was reflected over the line y=x. What should be the new coordinates of the point?
What is (4,-3)?
Line segment CD was dilated around the origin by a scale factor of 2. The endpoints of the image are C' (4,0) and D' (6,2). What are the coordinates of the endpoints of the original line segment?
What is C(2,0) and D(3,1)?
Describe the translation for this notation: (x,y) --> (x + 8, y + 4)
hat is a translation of 8 units to the right and 4 units up?
If coordinate A (-3,4) is rotated 90 degrees counter-clockwise, what is A'?
What is(-4, -3).
This property SOMETIMES changes under a rotation.
What is location
