what is a reflection?
A figure or point is flipped across a line on a coordinate plane.
100
what is a rotation?
Is when a figure or point is turned around a fixed point.
100
what is a translation?
A transformation in which a figure moves left,right,up and down
100
what is a dilation?
a transformation that reduces or enlarges a figure
100
what is the line of symmetry?
a line that divides a figure into mirror images
200
what is the center of rotation?
a fixed point about which a figure is isolated
200
A (1,5)
B(1,3) . translate it 4units left, and 6units down.
C(3,3)
D(3,5)
A prime(-3, -1)
B prime(-3, -3)
C prime(-1, -3)
D prime(-1, -1)
200
what is a reduction?
a dilation with a scale factor that is less than 1
200
What is rotational symmetry?
A figure that can be reflected over a line so that the image matches the original figure
300
what is the angle of rotation?
the number of degrees that a figure rotates
300
what is enlargement?
A dilation with a scale factor that is greater than 1
300
What is rotational symmetry?
a figure that can be rotated 180 degrees or less and exactly match its original figure
400
write all the rules for rotation
-90 degrees, the rule is (x, y) --------> (y, -x) -180 degrees, the rule is (x, y) --------> (-x, -y) -270 degrees, the rule is (x, y) --------> (-y, x)
