Rotation Rules/Terms
What is the sign change for 180 degrees counterclockwise?
(x,y) --- (-x,-y)
A point (3,5) is translated to (1,6). What is the translation?
-2,1
How many lines of symmetry does a square have?
4!
I rotated my pre-image 270 degrees, will I be back in the original position I was in?
Yes!
I am a transformation that can enlarge or reduce the size of a figure. I also involve scale factor. What am I?
I am a Dilation!
What is the sign change for 90 degrees clockwise?
(x,y) --- (y,-x)
If the points (9,4) were reflected over the x-axis, what would the new points be?
(9,-4)
Which definition describes Rotational Symmetry?
A. Tracking how many times an object when turned, overlaps itself.
B. Line drawn through a figure that cuts it into 2 equal areas which are mirror images of each other.
C. The exact angles of an object when rotated half way around a graph.
A. Tracking how many times an object when turned, overlaps itself.
(x,y) --- (x, y+4)
What is happening?
The point will go up 4 units.
I am a transformation that slides an coordinate/object across a coordinate plane. I also move all the points in the same direction and the same distance. What am I?
I am a Translation!
What is a Rotation?
A. A rotation is a transformation that involves solving scale factor.
B. A rotation is a transformation that turns a figure on a fixed point (origin)
C. A rotation is a transformation that involves tracking how many times a figure overlaps itself
B. A rotation is a transformation that turns a figure on a fixed point (origin)
The point (-5,2) is reflected over the y-axis. Where is the new point going to be located?
(5,2)
TRUE OR FALSE:
The term Order, means the number of terms
TRUE!!!
(x-y) ---(x+2,y-3)
What is happening in this transformation?
Right 2 units, and down 3 units.
I am a type of transformation where a figure is "flipped" over a line of symmetry. What am I?
I am a reflection!
A reflection produces a mirror image of a figure.
What is the sign change for 270 degrees counterclockwise?
**Hint: It is the same sign change for 90 degrees clockwise
(x,y) --- (y,-x)
What would be the new point you rotated (6,12), 90 degrees counterclockwise around the origin?
(-12,6)
What is the rotational order of a regular hexagon?
6!
A square is located in quadrant III, it is then rotated 90* clockwise around the origin. What quadrant is the square in now?
Quadrant II
I am the letter that represents the first number in an ordered pair. What am I?
X
What is the sign change for 270 degrees clockwise?
A. (x,y) --- (y,-x)
B. (x.y) --- (-x,-y)
C. (x,y) --- (-y,x)
C. (x,y) --- (-y,x)
What is a translation called before the transformation?
Pre-Image
What is the definition of Linear Symmetry?
Line drawn through a figure that cuts it into 2 equal areas, which are mirror images of each other.
How would you write a rule that will produce a translation that is 5 units to the right?
(x,y) --- (x+5,y)
If I go this direction, I will add to the y-coordinate.
I am going up!
