Properties of Rigid Transformations

Translated figures are always __________________.

• Congruent

• Bigger

• Smaller

• Rotated

A reflection ____________________.

• turns a figure around a point.

• slides an object form one place to another.

• flips or mirrors an object across a line.

• changes the size of an object.

Which answers are showing a reflection?

• a and c

• b and c

• c and d

• a and d

A transformation that “turns” a figure about a fixed point is a _____________________.

• rotation

• translation

• reflection

• dilation

What is the length of BH?

• 6

• 8

• 10

Identify the transformation from ABCD to A'B'C'D'.

• Translation

• Reflection across the x-axis

• Reflection across the y-axis

• 90^o counter clockwise rotation

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

Identify the transformation.

• Translations

• Reflection

• Rotation

• The image length is 7 units more than the preimage length.

• The image length is 1 unit more than the preimage length.

• The image length is 1 unit less than the preimage length.

• The image length is the same as the preimage length.

• After the reflection, rotation, and translation, the final image has all of the same angle measures.

• After the reflection and rotation, the angle measures are the same. But they change after the translation.

• After the reflection, the angle measures are the same. But they change after the rotation and translation.

• The angle measures change with each transformation.
