A polygon with all sides and angles equal.
What is a regular shape?
200
A transformation that moves points by sliding them on an axis.
What is a translation?
200
The main horizontal line on a coordinate plane.
What is the X-axis?

What is the formula for a reflection across the x-axis?
200
(-y,x) moved counterclockwise.
What is the formula of rotation for 90 degrees counterclockwise
200
A line where you could fold the image and each side matches perfectly.
What is a line of symmetry?
300
A transformation that moves points by reflecting them over an axis.
What is a reflection?
300
The main vertical line on a coordinate plane.
What is the Y-axis?
300
(-x,y)
What is the formula for a reflection across the y-axis?
300
(-y,x) Moved clockwise.
What is the formula of rotation 270 degrees clockwise?
300
When an image looks then same after it is rotated, under 360 degrees.
What is rotational symmetry?
400
A transformation that moves points by orbiting them around an origin.
What is a rotation?
400
The line in which an image is mirrored. Shapes are flipped across this line.
What is the line of reflection?
400
(x*a,y*b)
What is the formula for dilation?
400
(y,-x) Moved counterclockwise
What is the formula for a rotation 270 degrees counterclockwise?
400
Measured in degrees.
What is rotational symmetry measured in?
500
A transformation that changes the size of a figure.
What is a dilation?
500
The point at which is the center of the function on a coordinate plane.
What is the origin?
500
(y,x)
What is the formula of reflection across y=x?
500
(-x,-y) Moved clockwise
What is the formula for a rotation 180 degrees clockwise?
500
Lines of symmetry are lines that go through the shape that can be folded and exactly the same, rotational symmetry is the amount of times you can rotate something and it being in the exact same place as it was before.
What is the difference between lines of symmetry and rotational symmetry?
