# CreateArcAngles: Creates an arc of a circumference In LearnGeom: Learning Plane Geometry

## Description

`CreateArcAngles` creates an arc of a circumference

## Usage

 `1` ```CreateArcAngles(C, r, angle1, angle2, direction = "anticlock") ```

## Arguments

 `C` Vector containing the xy-coordinates of the center of the circumference `r` Radius for the circumference (or arc) `angle1` - Angle in degrees (0-360) at which the arc starts `angle2` - Angle in degrees (0-360) at which the arc finishes `direction` - String indicating the direction which is considered to create the arc, from the smaller to the higher angle. It has two possible values: "clock" (clockwise direction) and "anticlock" (anti-clockwise direction)

## Value

Returns a vector which contains the center, radius, angles (0-360) and direction (1 - "clock", 2 - "anticlock") that define the created arc

## Examples

 ``` 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15``` ```x_min <- -5 x_max <- 5 y_min <- -5 y_max <- 5 CoordinatePlane(x_min, x_max, y_min, y_max) C <- c(0,0) r <- 3 angle1 <- 90 angle2 <- 180 direction <- "anticlock" Arc1 <- CreateArcAngles(C, r, angle1, angle2, direction) Draw(Arc1, "black") direction <- "clock" Arc2 <- CreateArcAngles(C, r, angle1, angle2, direction) Draw(Arc2, "red") ```
