4/7/24 Transformation Review

If a rigid transformation is applied to a geometric figure, the resulting figure is called

• Translation

• Image

• Rotation

• Transformation

This takes every point of the figure to a point directly opposite to it on the other side of the line and the same distance from the line.

• Reflection

• Rotation

• Translation

• Dilation

Slides a figure without turning it. Every point in the figure goes the same distance in the same direction.

• Reflecltion

• Rotation

• Translation

• Dilation

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

What is the sequence of transformations?

• Reflect over the y then reflect over the x
• Reflect over the x then reflect over the y
• Translate 4 units then rotate 90˚
• Rotate 90˚ then reflect over the x

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

If the red triangle is rotated 180 degrees, then reflected over y=2 what is the final image?

• Green Triangle

• Blue Triangle

• Orange Triangle

• Red Triangle

Which of these segments could be an image of segment AB after a sequence of transformations? Check all that apply.

• CD

• GH

• JK

• LM

• NP

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

A turn is also called a ___________.

• Translation
• Reflection
• Rotation
• Transformation
