Flashcards do conjunto (17)
- 1Line of symmetrya line that divides a figure into two halves that are mirror
images of each other - 2Transformationto move or change a geometric figure in some way to produce a
new figure. - 3Translationa slide, simply means moving
- 4Rotationto turn an object
- 5Reflectiona rigid transformation in which the preimage is flipped across a line
of reflection to create the image. Each point of the image is the same distance
from the line as the preimage is, just on the opposite side of the line - 6Rigid MotionA transformation that preserves distance and angle measures
- 7Pre-imagethe original figure
- 8ImageThe new point, a line, a line segment, or figure after a transformation
- 9Clockwisein the same direction as the rotating hands of a clock
- 10Counterclockwisein the direction that is opposite of the direction the hands on
the clock move - 11R 90Rotation 90 degrees
(x,y) -> (-y,x) - 12R 180Rotation 180
(x,y) -> (-x,-y) - 13R 270Rotation 270o
(x,y) -> (y,-x) - 14r y=xReflection over line y=x ( x, y) ->(y, x)
- 15r y=-xReflection over line y=-x (x,y) = (-y,-x)
- 16r x-axisReflection over x-axis (x, y)-> (x, -y)
- 17r y-axisReflection over y-axis (x,y) -> (-x,y)
