100

A flip in math.

Reflection

100

True or False? Dilations always make a figure smaller. 

False

100

These two things make up the similar figures checklist. 

1) Proportional corresponding sides

2) Equal corresponding angles

100

Slope is the measure of this. 

Steepness

100

The sum of all interior angles in a triangle will always equal this number.

180^o

200

A slide in math.

Translation

200

A dilation might change the size of a figure's side lengths but never the _______.

angles

200

What geometric transformations can be used to prove similarity. 

1) Translations

2) Rotations

3) Reflections

4) Dilations

200

Slope is the change in ______ over _____.

Vertical distance (Y) over Horizontal distance (X)

Rise over run

200

If two triangles have _____ of their angles equal, the triangles are similar.

two / three

300

A turn in math.

Rotation

300

Dilations always produce ___________ figures.

similar

300

Congruent figures are _____ similar. 

(sometimes, always)

always

300

The slope of this line.

2/3


300

What is the measure of the missing angle?

35^o

400

Describing a translation requires these two things. 

1) Direction

2) Distance

400

Dilations need these two things.

1) Center Point of Dilation
2) Scale Factor

400

Similar figures are ____ congruent. 

(sometimes, always)

sometimes

400

The slope of this line. 

1

400

Similar or Not? Why?

Similar

500

Describing a rotation requires these three things. 

1) Center (Point)

2) Rotation angle (Degrees)

3) Direction (Clockwise or Counterclockwise)

500

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.

500

Dilations can result in a congruent figure if their scale factor is this number.
