# Angle: Computes the angle between three points In LearnGeom: Learning Plane Geometry

## Description

`Angle` computes the angle between three points

## Usage

 `1` ```Angle(A, B, C, label = FALSE) ```

## Arguments

 `A` Vector containing the xy-cooydinates of point A `B` Vector containing the xy-cooydinates of point B. This point acts as the vertex of angle ABC `C` Vector containing the xy-cooydinates of point C `label` Boolean. When `label` = `TRUE`, the plot displays the angle in the point that acts as the vertex. If missing, it works as with `label` = `FALSE`, so the angle is not displayed

## Value

Angle between the three points in degrees

## Examples

 ``` 1 2 3 4 5 6 7 8 9 10 11 12``` ```x_min <- -5 x_max <- 5 y_min <- -5 y_max <- 5 CoordinatePlane(x_min, x_max, y_min, y_max) A <- c(-1,0) B <- c(0,0) C <- c(0,1) Draw(CreatePolygon(A, B, C), "transparent") angle <- Angle(A, B, C, label = TRUE) angle <- Angle(A, C, B, label = TRUE) angle <- Angle(B, A, C, label = TRUE) ```

### Example output

```NULL
