Markers inside polygons

I'm using the code below to draw a polygon and print it on the map:

function initMap() {
        var map = new google.maps.Map(document.getElementById('map'), {
            center: {
                lat: -22.563923,
                lng: -44.1682872
            },
            zoom: 18,
        });

        var triangleCoords = [{
                lat: -22.563364,
                lng: -44.168448
            },
            {
                lat: -22.563663,
                lng: -44.169476
            },
            {
                lat: -22.564681,
                lng: -44.168978
            },
            {
                lat: -22.564388,
                lng: -44.167884
            },
            {
                lat: -22.563364,
                lng: -44.168448
            }
        ];


        var bermudaTriangle = new google.maps.Polygon({
            paths: triangleCoords,
            strokeColor: 'blue',
            strokeOpacity: 0.8,
            strokeWeight: .5,
            fillColor: 'blue',
            fillOpacity: .2
        });

        bermudaTriangle.setMap(map);

        google.maps.event.addListener(map, 'click', function (e) {
            var resultColor =
                google.maps.geometry.poly.containsLocation(e.latLng, bermudaTriangle) ?
                'red' :
                'green';

            new google.maps.Marker({
                position: e.latLng,
                map: map,
                icon: {
                    path: google.maps.SymbolPath.CIRCLE,
                    fillColor: resultColor,
                    fillOpacity: .2,
                    strokeColor: 'white',
                    strokeWeight: .5,
                    scale: 10
                }
            });
        });
    }

However, what I need is that when I click (or when a new point is added based on a array ) I know if it is outside or inside the polygon area.

The code was working, but stopped working when adding the line bermudaTriangle.setMap(map); because it draws an object on the map.

How can I tell if the point is inside or outside the polygon?
