Transformations

What transformation is this?

• rotation 90 degrees

• reflection y axis

• rotation 270 degrees

• translation 7 left and 9 down

What is the rule for rotation 180 degrees

• (X,Y) --> (X,Y)

• (X,Y) --> (-Y,X)

• (X,Y)--> (Y,-X)

• (X,Y) --> (-X,Y)

Reflect point A(4,5) over Y axis

• A'(4,-5)

• A'(-4,-5)

• A'(-4,5)

• A'(5,-4)

Reflect point B( -5,-7) over the X axis

• B'(-5,7)

• B'(5,7)

• B'(-5,-7)

• B'(7,-5)

What transformation is this

• reflection

• rotation

• translation

• dilation

translate the point A(2,4) 2 units up and 3 units right

• A'(5,6)

• A'(0,1)

• A'(4,1)

• A'(4,7)

A(10,12) --> A'(12,-10). What transformation is this?

• Rotation 90 degrees

• Rotation 270 degrees

• Reflection in Y axis

• Reflection in X axis

What transformation is this?

• reflection in x axis

• rotation 90 degrees

• reflection in y axis

• dilation scale factor 2

what is the rule for this translation?

• 8 right 4 up

• 8 left 4 up

• 7 right 3 down

• 3 up 2 right

Dilate point A (3,7) by a scale factor of 2

• A'(3,-7)

• A'(-3,7)

• A'(5,9)

• A'(6,14)
