Transformations

If the dotted figure is the image, the original figure was reflected over the ...

• x-axis
• y-axis

State the line of reflection.

• Reflection across y-axis
• Reflection across x-axis
• Reflection across x = 1
• Reflection across y = 1

Triangle ABC will be dilated by a scale factor of 1/2.  What will be the coordinates of C'?

• (-1, -2.5)
• (12, 6)
• (3, -1.5)
• (0, 1.5)

Enlargement or reduction?  Find the scale factor!

• It's a reduction; the scale factor is 2.
• It's an enlargement; the scale factor is 2.
• It's an enlargement; the scale factor is 1/2.
• It's a reduction; the scale factor is 1/2.

What type of transformation is this?

• Rotation

• Reflection

• Translation

• Enlargement

What type of transformation is this?

• Rotation

• Reflection

• Translation

• Enlargement

Write a rule for the translation.

•  (x -1, y  + 2)
•  (x -2, y  + 1)
•  (x +2, y  - 1)
• (x +1, y  -  2)

Triangle ABC is going to be translated. How is ABC being translated if the rule (x,y) --> (x+3, y-2) is used?

• 3 up and 2 left
• 3 right and 2 down
• 3 left and 2 up
• 3 right and 2 up 

How is triangle ABC being translated to triangle A'B'C'?

• (x, y) --> (x - 8, y + 3 )
• (x, y) -->(x - 4, y - 9) 
• (x, y) --> (x + 8, y - 3) 
• (x, y) --> (x+ 4, y - 9) 

Determine where T' would be if you translated T three units to the right and six units up.

• (5, 1)
• (2, -5)
• (-1, 1)
• (8, -2)
