Pencil Code Reference > rt

# rt turns the turtle right

`rt`

pivots the turtle clockwise (`rt`

stands for "right turn").

The turn is measured in degrees.

rt 90

Notice that the turtle will not actually move in the new direction
until you tell it to move forward with `fd`

.

### Drawing Angles

When using a pen, putting `rt`

between two `fd`

moves can draw an angle.

fd 100
rt 120
fd 100

Notice that the angle used by `rt`

is the *exterior* angle.
The interior angle added to the exterior angle will be 180.
For example, the 60 degree interior angle drawn by the program
above corresponds to the 120 degree exterior angle swept out by
the turtle.

### Turning an Upside-Down Turtle

`rt`

turns right from the turtle's point of view, so
if the turtle is facing downward, when it turns right from its
point of view, it will end up facing left from your point of
view. The demo below can be clicked a few times to show
different starting directions.

### Drawing Curves

`rt`

can also be used to draw curves by using a second argument.
Read the reference page on arcs.
