Implementations

impl Tri

pub fn new(s1: f64, s2: f64, s3: f64) -> Tri

Returns a new Tri from given sides s1, s2, s3.

Examples

let tri = polys::Tri::new(24.0, 30.0, 18.0);

Trait Implementations

impl Debug for Tri

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Polygon for Tri

fn area(&self) -> f64

Gets the area of the Tri from its sides.

Examples

let tri = polys::Tri::new(24.0, 30.0, 18.0);
let area = tri.area();
assert_eq!(area, 216 as f64);

fn peri(&self) -> f64

Gets the perimeter of the Tri from its sides.

Examples

let tri = polys::Tri::new(24.0, 30.0, 18.0);
let peri = tri.peri();
assert_eq!(peri, 72f64);
