Answer the question in this figure.

• This is a reflection over the line "l"

• This is a $90\degree\$ rotation

• This is a $180\degree$ rotation at the common point between the figures.

• This is a reflection over itself

This diagram shows what transformation?

• This is a reflection of "A" over line L

• This is a rotation of "A" around a point on line L

• This is a rotation of "A" around one of the vertices.

• This is a translation to the fight and then a rotation of $90\degree$ clockwise.

This transformation is what?

• This is a rotation.

• This is a translation.

• This is a reflection.

• The figures are not the same shape so this is not a rigid transformation.

Here is a grid showing triangle ABC and two other triangles. You can use a rigid transformation to take triangle ABC to one of the other triangles. Which one? How?

• Triangle EBD - ABC is reflected on a line at point "B"

• Triangle CFG - Translate triangle ABC 7 units right so that "B" matches up with "F". Then rotate 90 degrees clockwise around "F".

• Triangle CFG - Rotate triangle ABC 90 degrees counterclockwise around point "C", then rotate 180 degrees around the midpoint of segment CG.

• Triangle EBD - Translate triangle ABC up two units.

Here are two line segments. Is it possible to rotate one line segment to the other? If so, find the center of such a rotation.

• Yes, it is possible to rotate one of these line segments to the other. This can be done by rotating $180\degree$ around a point midway between the two lines.

• No, is not possible to rotate because the only way to get one line to the other is by a translation up 5 units and then right two units.
