Transformation Reteach

​Rigid Transformations Reteach

By Christi Rankin

I can

-identify translations, reflections, and rotations.
-translate a geometric figure and write the rule.
-reflect a geometric figure in respect to the x and y axis and write the new coordinates.
-rotate a geometric figure around the origin and identify the new coordinates.
-identify congruent angles and line segments in the preimage and its image.

Multiple Choice

The dashed figure is the image of the solid figure.  What is the Algebraic Notation for the Translation?

• (x, y) --> (x - 7, y + 4)
• (x, y) --> (x + 7, y - 4)
• (x, y) --> (x + 4, y - 7)
• (x, y) --> (7x, 4y)

Multiple Choice

What would be the coordinates of point K if it was reflected over the x-axis?

• (-5, -2)

• (-5, 2)

• (5, -2)

Multiple Choice

Identify the transformation from A to D.

• 90^o Clockwise Rotation
• 180^o Rotation
• 270^o  clockwise Rotation
• 360^o Rotation

Multiple Choice

What is the angle of the clockwise rotation?

• 90°

• 180°

• 270°

Multiple Choice

Which correctly describes the two transformations that were used to create the image on the graph?

• Reflection over the y-axia and a rotation 90^o counter clockwise

• (x+10, y) and reflection over x-axis

• Rotation 90^o clockwise and a reflection over the x-axis

• Reflection over the x-axis ad a translation (x+6,y)

Multiple Choice

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

• a reflection followed by a translation

• a translation followed by a rotation

Multiple Choice

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

• translation then rotation

• translation then reflection

• rotation then reflection
