Describing a translation requires these two things.
1) Direction
2) Distance
Dilations need these two things.
1) Center Point of Dilation
2) Scale Factor
Similar figures are ____ congruent.
(sometimes, always)
sometimes
The slope of this line.
1
Similar or Not? Why?
Similar
Describing a rotation requires these three things.
1) Center (Point)
2) Rotation angle (Degrees)
3) Direction (Clockwise or Counterclockwise)
How will dilating a figure with a scale factor of 1/3 change a figure?
It will make the figure 3 times smaller from the center of dilation.
Dilations can result in a congruent figure if their scale factor is this number.
1
