200
When you rotate a figure, what is the point that it rotates around called.
What is the center of rotation.
200
Which transformation does not result in a congruent figure?
What is dilation.
300
When a figure is ENLARGED (gets bigger) or REDUCED (gets smaller)
What is dilation.
300
Describe how this point was translated:
A (1,5) A' (0,-5)
What is 1 unit left and 10 units down.
or (x -1, y -10)
300
Find the new coordinates of (3,-2) after you reflect the point over the x-axis.
What is (3,2).
300
What are the new coordinates of (5,4) after you rotate a point 180º?
What is (4,5).
300
Name the 3 basic rigid motions.
What are, reflection, rotation, translation.
400
Transformations in which the pre-image and image are congruent
What is a basic rigid motion.
400
Write the notation of point (x,y) after it moves 3 spots to the left and 7 spots up.
(X-3, y + 7).
400
Write the notation of point (x,y) after it is reflected over the y-axis.
What is (-x,y).
400
What are the 2 Ds of rotation?
What are direction and degree.
400
Name is transformation:
What is dilation.
500
Vertical axis on a coordinate plane
What is the y-axis.
500
Describe the translation for this notation: (x,y) --> (x + 8, y + 4)
What is, 8 units right and 4 units up.
500
What is the line of reflection that maps point A with A'?
A(-3,12) A'(-3,-12)
What is the x-axis.
500
If point A(3,-4) is rotated 90 degrees clockwise, what quadrant will it end up in.
BONUS 500: What is the ordered pair of A'?
What is quadrant III.
BONUS: (-4,-3)
500
If point P(3,2) is reflected over the y-axis and then rotated 180 degrees, where will the point end up?
(write the new ordered pair)
What is (3,-2).
Explanation:
P(3,2) becomes(-3,2) because (-x,y)
then (-3,2) becomes (3,-2) because (-x,-y)
