A flip in math.
Reflection
True or False? Dilations always make a figure smaller.
False
These two things make up the similar figures checklist.
1) Proportional corresponding sides
2) Equal corresponding angles
Slope is the measure of this.
Steepness
The sum of all interior angles in a triangle will always equal this number.
180^o
A slide in math.
Translation
A dilation might change the size of a figure's side lengths but never the _______.
angles
What geometric transformations can be used to prove similarity.
1) Translations
2) Rotations
3) Reflections
4) Dilations
Slope is the change in ______ over _____.
Vertical distance (Y) over Horizontal distance (X)
Rise over run
If two triangles have _____ of their angles equal, the triangles are similar.
two / three
A turn in math.
Rotation
Dilations always produce ___________ figures.
similar
Congruent figures are _____ similar.
(sometimes, always)
always
The slope of this line.
2/3
What is the measure of the missing angle?
35^o
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
True or False: When writing slope as a number we prefer to write the slope as an improper fraction or as a whole number if we can.
These two triangles are similar. Find the missing side lengths.
