# NAME

Geometry::Primitive::Arc - Portion of the circumference of a Circle

# DESCRIPTION

Geometry::Primitive::Arc represents a closed segment of a curve.

# SYNOPSIS

```
use Geometry::Primitive::Arc;
my $arc = Geometry::Primitive::Arc->new(
angle_start => 0,
angle_end => 1.57079633,
radius => 15
);
```

# ATTRIBUTES

## angle_start

The starting angle for this arc in radians.

## angle_end

The ending angle for this arc in radians.

## radius

Returns the radius of the arc.

## origin

Set/Get the origin of this arc.

# METHODS

## new

Creates a new Geometry::Primitive::Arc

## get_point_at_angle

Given angle in radians returns the point at that angle on this arc. Returns undef if the angle falls outside this arc's range.

## length

Returns the length of this arc.

## point_end
