Transformations Triangles

Name the series of transformations that maps ABC onto DEF

• reflect over x then translate left 6 up 1

• reflect over y then translate down 6 left 1

• translate right 6 down 1, then reflect over x

• rotate 90 clockwise then reflect over y

Tell whether the transformation is a dilation. Explain.

• No, scale factor isn't the same.

• Yes, scale factor is the same.

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

• Green Triangle

• Blue Triangle

• Orange Triangle

• Red Triangle

What sequence of transformations could map ∆ABC onto its image ∆A''B''C''?

• a reflection followed by a rotation

• a reflection followed by a translation

• a translation followed by a rotation

• a translation followed by a reflection

Which of the following describes the sequence of transformations shown?

• Reflect across the x-axis and then rotate 90 degrees clockwise around the origin

• Rotate 90 degrees clockwise around the origin and then translate down.

• Reflect across the x-axis and then reflect across the y-axis.

• Translate up and then rotate 90 degrees counterclockwise about the origin.

Which transformation is shown?

• Translation

• Reflection over the x-axis

• Reflection over the y-axis

• 180^o rotation

Which transformation is shown?

• Translation

• Reflection over the x-axis

• Reflection over the y-axis

• 90^o clockwise rotation

Which of the statements is true about the graphed triangles?

• They are similar, because one can be obtained by dilating the other about the origin with a scale factor of 2.

• They are similar, because one can be obtained by dilating the other about the origin with a scale factor of 1/2.

• They are not similar, because one can be obtained by dilating the other about the origin with a scale factor of 2.

• They are not similar, because one can be obtained by dilating the other about the origin with a scale factor of 1/2.

What sequence of transformations could map ∆ABC onto its image ∆A''B''C''? (Remember: You're transforming from purple, to green, to red.)

• a reflection followed by a rotation

• a reflection followed by a translation

• a translation followed by a rotation

• a translation followed by a reflection

Identify the sequences of transformations from the green image to the red image to the blue image.

• rotation then translation

• translation then rotation

• translation then reflection

• rotation then reflection
