polygon-info

properties of regular polygons.

Usage

Install with npm

npm i polygon-info

modules

1.polygonInfo

2.nPolygonInfo

3.polygramTriangles

1.polygonInfo

takes a single argument - sides ,of type number and returns a promise

import {polygonInfo} from "polygon-info";

const triangle = await polygonInfo(3);

// triangle; 
//
// {
//  sides: 3,
//  interiorAngle: 60,
//  exteriorAngle: 120,
//  sumOfInteriorAngles: 180,
//  sumOfExteriorAngles: 360,
//  interiorAngleHalf: 30,
//  exteriorAngleHalf: 60,
//  diagonals: 0,
//  characteristicTriangle: [ 30, 30, 120 ],
//  angleData: [ 60, 120, 30, 60, 60 ]
// }

2.nPolygonInfo

takes a single argument - n ,of type number and returns a promise, when resolved returns polygon data same as from module polygonInfo but for n no of polygons.

import {nPolygonInfo} from "polygon-info";

const nPolygonData = await nPolygonInfo(10);

3.polygramTriangles

takes a single argument - angleData , of type array and returns a promise, when resolved returns polygram triangles data , different types of triangles (NOT total triangles) present in a polygram, including the one that is obtained by dividing the polygon from the center. angleData is provided by either polygonInfo or nPolygonInfo module.

import {polygonInfo, polygramTriangles} from "polygon-info";

const {angleData} = await polygonInfo(7);
const polygramTriangles = await polygramTriangles(angleData);
 
 // polygramTriangles;
 //
