A flip in math.
Reflection
True or False? Dilations always make a figure smaller.
False
True or False? When two figures are congruent then they have the same side lengths and angles.
true
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
True or False? When two figures are similar, they are exactly the same in all ways.
False
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
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
These two triangles are similar. Triangle ABC was scaled with a scale factor of 1.5. If side FE is 5 units long, what is the length of CB?
7.5 units
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.
Triangle ABC ~ Triangle DEF
If the largest angle in triangle ABC is 90 degrees, then what is the largest angle in Triangle DEF?
90 degrees
These two triangles are similar. Find the missing side lengths. Also , angle ACB is 90 degrees and angle RST is 27 degrees, what is the measure of angle BAC?
s=12
t=15
angle BAC = 63 degrees
