Best Answer

That depends upon the centre of rotation - it can be any point at all in the plane; eg:

If the centre is (-1, -2), then after the rotation (-1, -2) → (-1, -2)

If the centre is (-0, 0), then after the rotation: (-1, -2) → (2, -1)

If the centre is (1, 2), then after the rotation: (-1, -2) → (5, 0)

etc.

90 = 9.0 x 10^(1)

With a scale factor of 1, the image is exactly the same size as the original object.

The 4 classifications are:- 1 Acute angle which is greater than 0 but less than 90 degrees 2 Right angle which is 90 degrees 3 Obtuse angle which is greater than 90 but less than 180 degrees 4 Reflex angle which is greater than 180 but less than 360 degrees A full rotation is 360 degrees

One-sixth

The factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90.The prime factorisation useful for finding the factors of 90, and the lowest common multiple and highest common factor of 90 with other numbers is 90 = 2 x 3² x 5.The factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90.The factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45 and 90.The factors of 90 are: 1, 2, 3, 5, 9, 10, 18, 30, 45, & 90

The answer will depend on whether the rotation is clockwise or counterclockwise.

The answer depends on the centre of rotation. A rotation cannot be described without specifying the centre of rotation.

It is (-1, 6).

(-1, -4) rotated 90 degrees anticlockwise

The coords are (6, 1).

It is (-6, -1).

It is (6, 1).

It is 1/4 of a turn

90 degrees is a 1/4 of a full rotation of 360 degrees

It is (-1, 6).Also, if the rotation is 180 degrees, then clockwise or anticlockwise are irrelevant.It is (-1, 6).
