Transformations


translation• move every point from afigure the same directionand same distance


write the rule for thetranslation


Rotation• a transformation in which afigure is turned about a fixedpoint called the center ofrotation• all rotations in geometry arecounterclockwise


Rules for Rotations aboutthe Origin(a,b) -> 90 (-b,a) ->180 (-a,-b) -> 270 (b,-a)


Rotate 270


Rules for Reflections• If (a,b) is reflected on the x-axis, its reflectionis (a,-b)• If (a,b) is reflected on the y-axis, its reflectionis (-a,b)• If (a,b) is reflected on the line y=x, itsreflection is (b,a)• If (a,b) is reflected on the line y=-x, itsreflection is (-b,-a)
