Jan 23~ Translations, rotations, reflections

The red triangle represents what type of rotation:

• 180° Clockwise
• 90° Clockwise
• 90° Counter Clockwise
• 270° Clockwise

If you were to rotate ABCD 90° counterclockwise about the origin, what would the coordinate of A' be?

• (-5, 5)
• (-3, 5)
• (-5, 3)
• (-3, 3)

Rotate the point (7,8) around the origin 90 degrees counterclockwise.
State the image of the point.

• (-7,-8)
• (8,-7)
• (-8,7)
• (8,7)

Reflect (6, -3) over the line x-axis.

• (6, 3)
• (-6, -3)
• (-3, 6)
• (3, -6)

Determine how to translate triangle A'B'C' to triangle ABC.

• (x+2, y-5)

• (x-2, y+9)

• (x-2, y-9)

Reflect Point C over the y-axis:

• (-3, 2)
• (3,2)
• (-2,3)
• (3,0)

Determine where X' would be if you translated 3 units to the left and 9 units down.

• (-4, 4)
• (-10, 2)
• (-4, -5)
• (-1, 5)

How is trapezoid ABCD translated to trapezoid A'B'C'D'?

• Translated 5 units down and 5 units to the right
• Translated 5 units down and 1 to the right
• Translated 8 units down and 5 units to the right
• Translated 5 units down and 4 units to the right

Write a rule for the translation.

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

Which way do you rotate if you turn to the right?

• Clockwise

• Counter-clockwise

• upside down

• flip-flop
