Translations
Change the preimage point (1,4) with the
rule (x,y)→(x-1,y+4).
What is (0,8)?
A rotation is what.
What is a transformation when a figure rotates around a fixed point?
A reflection is this.
What is a flip over a line, preferably the x or y axis?
This rule (x,y)→(-x, y) is used for this kind of transformation.
What is a reflection over the y-axis?
A rectangle with the points (10,3) (3,10) (10,10) and (3,3) gets translated 5 units left and 4 units down. How many right angles should the image have?
What are 4 right angles?
A center of rotation is usually this point.
What is (0,0)?
Point G is located at (2, 1). Point H is at (2,-1). What axis was point G reflected over to create point H?
What is the x-axis.
This rule, (x,y)→(-x,-y) can be used for these transformations.
What are reflection over both axis and rotation 180 degrees in either direction?
Must include both options to let it count
Triangle ABC was translated 3 units left and 4 units down to Triangle A`B`C`. Write a triangle congruence statement to compare the triangles?
Point A is located at (2,1). Now the coordinates of Point A`, when rotated around the origin 360 degrees clockwise, is this.
What is (2,1)?
Reflect Line Segment GH, With the coordinates of (12, 12) and (10, 9) over the x-axis.
What is (12, -12) and (10, -9)?
This rule, (x,y)→(y,-x), is used for which rotation counterclockwise.
What is 270 degrees?
Triangle DEF has the points (3,4) (9, 4) (9,6). Triangle D`E`F` has the points (3,2) (9,2) (9,4). Triangle DEF followed this rule to make Triangle D`E`F.
What is (x,y)→(x,y-2)?
Line Segment AB is located in quadrant I. After a 90 degree clockwise rotation, what quadrant is line segment AB in?
What is quadrant IV
Daily Double:
Reflect Polygon HGFE,(3,9)(9,8)(4,5)(2,19) over both axis.
What is (-3,-9)(-9,-8)(-4,-5) and (-2,-19)?
OkThe rule (x,y)→(y,-x) is for a clockwise rotation to what degree.
What is 90 degrees?
Daily Double:
Quadrilateral EFGH has the points (0,0)(1,1)(-1,9)(2,-3). Quadrilateral E`F`G`H` follows the rule (x,y)→(x-4,y-4) and has these coordinates.
What is (-4,-4)(-3,-3)(-5,5)(-2,-7)?
Polygon ABC is located at (3,9) (4,8) and (9,2). When rotated around the origin by 180 degrees, what are the new coordinate points of polygon ABC?
What are (-3,-9),(-4,-8) and (-9,-2)
Where is the point (0,0)after a reflection over both axis.
What is (0,0)?
The rule (x,y)→(-x,-y-2) demonstrates what sequence of transformations.
What is reflection over both axis and a translation 2 down?
Any equivalent answers also count.
