What is the equation to find the angle of rotational symmetry?
Angle of Rotational Symmetry = 360 / Order of Rotation
The image moves 6 units down and 3 units to the left
Which transformation does not preserve congruence?
Dilations
(5,-10)
2 lines of symmetry and both the x and y axises
45, 90, 135, 180, 225, 270, 315, 360
A'(9,8), B'(1,4), C'(-1,8)
What does a scale factor do to an image? (be incredibly specific)
-When scale factor is > 1, it makes the image bigger.
-When scale factor is > 0 but < 1, it makes the image smaller

x = 0
51.43, 102.86, 154.29, 205.72, 257.15, 308.58, 360
A'(-2,5), B'(-6,2), C'(-6,4), D'(-2,1)
Scale Factor = 2
Triangle ABC rotates 90 degrees counterclockwise or 270 degrees clockwise. Then, triangle A'B'C' is reflected over the x-axis to create triangle A''B''C''.
(-5,2)
C. (x,y) -> (-x,-y)
D. (x-3, y+6)
Side AB and Side CD = 50. Side AC and BD = 17
A'(3,2), B'(7,-6), and C'(3,-7)
A''(7,2), B''(11,-6), and C''(7,-7)
The triangle should be in the third quadrant. A'(-2,-3), B'(-1,-3), and C'(-1,-1)
Area = 930.15
Perimeter = 125.7
