In the three geometric scenarios, space-time might bend in on itself, be flat or bend outwards – and the angles of a triangle would either exceed, be equal to or be less than 180°
Closed Universe >180°
(positive curvature)
Flat Universe =180°
(zero curvature)
Open Universe <180°
(negative curvature)
