Transformations - Isometries

What is the rule for the translation?

• (x,y) --> (x+9, y-4)

• (x,y) --> (x-9, y-4)

• (x,y) --> (x+ 9, y+4)

• (x,y) --> (x -9,y+4)

Select all that apply. What are the two transformations in a glide reflection?

• glide

• translation

• rotation

• reflection

• dilation

Congruent geometric figures have the:

• Same size
• Sides Equal
• Same Size and Same Shape
• Angles Equal

Under what composition of transformations does triangle ABC map onto triangle A''B''C''

• Reflection over x-axis, then Rotation of 90 Degrees

• Rotation of -90 Degrees, then Reflection over y-axis

• Reflection over y-axis, then Rotation of -90 Degrees

• Rotation of 90 Degrees, then Reflection over x-axis

Identify the transformation from ABC to A'B'C'.

• 90^o clockwise rotation
• 90^o counter clockwise rotation
• Reflection across the y-axis
• Reflection across the x-axis

Describe the transformation.

• translation: right 4 and up 6
• reflection across x=-2
• translation right 6 and down 1
• reflection across y=-2

• (-1,5)
• (5,-1)

What transformation is shown?

• A 90 degree CW rotation.

• A reflection across y = x

• A reflection across y = -x

• A 90 degree CCW rotation

• A reflection across x = -2
