ee.Geometry.edgesAreGeodesics
Returns true if the geometry edges, if any, are geodesics along a spherical model of the earth; if false, any edges are straight lines in the projection.
| Usage | Returns |

Examples
// Define a Geometry object.
var geometry = ee.Geometry({
'type': 'Polygon',
'coordinates':
[[[-122.081, 37.417],
[-122.086, 37.421],
[-122.084, 37.418],
[-122.089, 37.416]]]
});
// Apply the edgesAreGeodesics method to the Geometry object.
var geometryEdgesAreGeodesics = geometry.edgesAreGeodesics();
// Print the result to the console.
print('geometry.edgesAreGeodesics(...) =', geometryEdgesAreGeodesics);
// Display relevant geometries on the map.
Map.setCenter(-122.085, 37.422, 15);
Map.addLayer(geometry,
{'color': 'black'},
'Geometry [black]: geometry');

geemap for interactive development.
