rotation practice

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)

Answer explanation

Find the image of triangle ABC after rotating 90 degrees counterclockwise about the origin. What are the coordinates of C' ?

• (3, -4)

• (-4, -3)

• (4, 3)

• (-3, 4)

Answer explanation

What would be the location of A' after a 90 degree counterclockwise rotation of point (A) ?

Hint: Look for point A and apply the rule (x, y) → (–y, x)

• (-1, 2)

• (2, -1)

• (-2, -1)

• (-1, -2)

If point (5,2) is rotated counterclockwise 90° about the origin, its image will be point.

• (2,5)

• (2,-5)

• (-2,5)

• (-5,-2)

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)

The red triangle represents what type of rotation:

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

The red triangle represents what type of rotation:

• 180° Clockwise
