Q: 300
Define reflection symmetry
A: 300
When an object can be flipped over a line of symmetry to produce a mirror image
Q: 400
How many lines of symmetry does the following figure
have?
A:400
Q:500
Reflect the triangle over the y-axis and give the coordinates
of the reflected image.
A:500
(9,9)
(5,1)
(3,6)
Q:100
True or FalseRotation symmetry will
always have a line of symmetry
A:100
Q:200
What is the name of the fixed point about which you rotate a figure?
A: 200
Center of Rotation
Q: 300
What is the angle of rotation for the blades of the windmill?
A: 300
Q: 400
If point A is (-19,7), give the ordered pair of A’ rotated
180 degrees.
A: 400
Q: 500
A triangle has the following vertices: A(-2, 3) B(-5, -7) C(6,8). Rotate triangle ABC 90 degrees counterclockwise and give the new coordinates.
A: 500
A’(-3,-2)
B’(7,-5)
C’(-8, 6)
Q: 100
True or FalseThe following is an example
of translation symmetry.
A: 100
Q: 200
Describe translation symmetry
A: 200
• When you can slide the whole design to a position in which it looks exactly the same as it did in the original position.
Q: 300
Describe the direction you would slide a figure if the figure was translated by (-4, 9)
A: 300
• The figure would move four units to the left and up nine units
Q: 400
Give the ordered pair of point G(-3, -12) translated by
(4,8).
A: 400
G’(1, -4)
Q: 500
Given points R(18, -7) and R’(11, 11), determine the ordered pair
point R was translated by to get R’• Be able to explain how you got your
answer
A: 500
• Take the coordinates of the copy minus the coordinates of the original
• R’(11,11) 11-18= -7
• R(18, -7) 11- -7= 18

Q:100• _____________ when an object can be
bisected to form two congruent shapes
A: 100
• Line Symmetry
Q: 200
__________________ symmetry is when an object can be turned less than 360˚ around its center point so that it looks as it did in its original position.
A: 200
• Rotation
Q: 300
•Contrast similar and congruent figures
A: 300
• Similar figures are the same shape, but not the same size
• Congruent figures are the same size and shape
Q: 400
• Define what a transformation is and give 3 examples
A: 400
• Movements of geometric figures
• Reflection, Rotation, Translation
Q: 500
Explain angle of rotation
A: 500
• The angle of rotation is the smallest angle through which you can turn the figure in a clockwise or counterclockwise direction so that it looks the same as it does in its original position.
• 360˚ ÷ (# of turns) = angle of rotation
Q: 100• Describe the location of the four quadrants

Q: 200
Match the types of symmetry to the following terms:
1. Slide
2. Turn
3. Flip
A: 200
1. Slide – Translation
2. Turn – Rotation
3. Flip- Reflection
Q: 300
• What type of symmetry does the following figure have?
A: 300
• None
Q: 400
• Translate the figure below by (5, -6) and list the ordered pairs of the copied image.
A: 400
• (-9, 9) + (5, -6) = ‘(-4, 3)
• (-5, 1) + (5, -6) = ‘(0, -5)
• (-3, 6) + (5, -6) = ‘(2, 0)
Q: 500
What is the angle of rotation of a perfect circle? Explain.
How many lines of symmetry does a perfect circle have? Explain.
A: 500
The angle of rotation of a perfect circle could be anywhere between 0˚ and 360˚
A perfect circle could have infinite lines of symmetry through the center point
