Which transformation happened?

• translation

• reflection

• rotation

Describe the transformation.

• translation (x-1, y+4)

• rotation of 180 degrees

• reflect across x = 4

• translation (x+4, y-1)

In which case does the transformation of △𝑄𝑅𝑆 result in an image △𝐷𝐸𝐹 where ∠𝑄≅∠𝐷,∠𝑅≅∠𝐸,∠𝑆≅∠𝐹, and 𝑄𝑅𝐷𝐸=𝑄𝑆𝐷𝐹=𝑅𝑆𝐸𝐹≠1 ?

• A. a translation of 6 units to the left and 8.5 units up followed by a reflection over the line 𝑦=2𝑥

• B. a reflection over the line 𝑦=−2𝑥 followed by a translation of 6.5 units to the right and 3.5 units down

• C. a rotation of 45° clockwise about vertex 𝐴 followed by a dilation by a scale factor of 0.95 about the origin.

• D. a dilation by a scale factor of 1 about the origin followed by a rotation of 45° clockwise about vertex 𝐴

• A

• B

• C

• D

How would you describe this tranformation?

• rotation of 90 degrees

• reflection across x-axis

• reflection across y-axis

• translation right 6

Transformations are when you

• turn, flip, or slide a shape on a graph

• erase a shape on a graph

After a transformation, the shape still has the same size, area, angles and line lengths.

• True

• False

This is an example of

• a reflection

• a rotation
