The demonstration below that shows you how to easily perform the common Rotations (ie rotation by 90 , 180 , or rotation by 270) . There is a neat 'trick' to doing these kinds of transformations. The basics steps are to graph the original point (the pre-image), then physically 'rotate' your graph paper, the new location of your point represents the coordinates of the image. It's much easier to understand these steps if you watch the visual demonstration below.

Plot the original point on graph paper

Turn or 'rotate' your graph paper by the amount you are asked to rotate : °

Label the new Coordinates the cordinates of the image!

You can drag the point anywhere you want

How To Perform Rotations The Easy Way (Mouse Over To Start)

Rotation by 90° about the origin: R(origin, 90°)

A rotation by 90° about the origin can be seen in the picture below in which A is rotated to its image A'. The general rule for a rotation by 90° about the origin is (A,B) (-B, A)

Rotation by 180° about the origin: R(origin, 180°)

A rotation by 180° about the origin can be seen in the picture below in which A is rotated to its image A'. The general rule for a rotation by 180° about the origin is (A,B) (-A, -B)

Rotation by 270° about the origin: R(origin, 270°)

A rotation by 270° about the origin can be seen in the picture below in which A is rotated to its image A'. The general rule for a rotation by 270° about the origin is (A,B) (B, -A)

Rotation by 90° about the origin: R(origin, 90°)

A rotation by 90° about the origin can be seen in the picture below in which A is rotated to its image A'. The general rule for a rotation by 90° about the origin is (A,B) (-B, A)

Rotation by 180° about the origin: R(origin, 180°)

A rotation by 180° about the origin can be seen in the picture below in which A is rotated to its image A'. The general rule for a rotation by 180° about the origin is (A,B) (-A, -B)

Rotation by 270° about the origin: R(origin, 270°)

A rotation by 270° about the origin can be seen in the picture below in which A is rotated to its image A'. The general rule for a rotation by 270° about the origin is (A,B) (B, -A)

After any of those transformations (turn, flip or slide), the shape still has the same size, area, angles and line lengths.

When one shape can become another using only Turns, Flips and/or Slides, then the two shapes are Congruent

When a Resize is neeeded for one shape to become another (we may also Turn, Flip and/or Slide) the two shapes are

In other words:

When one shape becomes another ...

The shapes are ...

... using only Rotate, Reflect and/or Translate

... using a Resize (may also Rotate, Reflect
