Rotations

If A(6, -1) is rotated 90° counterclockwise about the origin, what are the coordinates of A'?

If C(7, 4) is rotated 270° counterclockwise about the origin, what are the coordinates of C' ?

C' is (​ (a)   ,​ (b)   )

Use the points A(6, -1), B(-3, -2), C(7, 4), D(-8, 5), and E(2, -9).

• (-5, -8)

• If E is rotated 90° clockwise about the origin, what are the coordinates of E'?

• (-2, 3)

• If D is rotated 180° about the origin, what are the coordinates of D?

• (8, -5)

• If B is rotated 270° counterclockwise about the origin, what are the coordinates of B'?

• (-9, -2)

• If D is rotated 90° counterclockwise about the origin, what are the coordinates of D'?

• (9, 2)

• If E is rotated 90° counterclockwise about the origin, what are the coordinates of E'?

If C(7, 4) is rotated 180° about the origin, what are the coordinates of C'? Plot the point.

Plot A' if A(6, -1) is rotated 180° about the origin.

If C is rotated 270° clockwise about the origin, what are the coordinates of C'?

Which point correctly shows where D' is after D(-8, 5) is rotated 90° clockwise about the origin?

Use the points A(6, -1), B(-3, -2), C(7, 4), D(-8, 5), and E(2, -9) to answer the following questions.

1. 1. Label B' if B is rotated 180°.

2. 2. Label B'' if B is rotated 270° clockwise.

3. 3. Label A' if A is rotated 90° clockwise.

4. 4. Label E' if E is rotated 180°.
