A planetary nebula is formed when a low to intermediate mass star approaches the end of its life. Before the ejected materials finally being one with the insterstellar matters, a nebula will be visible surrounding its former stellar core. The variety of planetary nebulae visual appearances indicate that the matters leave behind the central star in unique ways. An idea which is always interesting about planetary nebulae is deducting its actual three dimensional shape. Morphokinematics study aims to find out the 3D shape using the help of imaging and spectroscopy. From imaging of the planetary nebulae, one can observe the projection created by the relative position of the planetary nebulae and the observer. On the other hand, spectroscopy gives the ability to infer the expansion characteristic from the spectrum it produced. This thesis aims to determine the 3D shape of Sh 2-71 using images obtained from Gemini Multi-Object Spectrograph (GMOS), and Hong Kong/Australian Astronomical Observatory/Strasbourg Observatory Halpha Planetary nebula (HASH PN) combined with high resolution long slit spectra from San Pedro Martir Kinematic Catalogue of Planetary Nebulae. The 3D modelling is carried out with a software specializes in modelling three dimensional astrophyisical object SHAPE. The acquired data from observations show that Sh 2-71 possesses a torus with three bipolar lobes while modelling by SHAPE tells that the torus is inclined by 37o and the bipolar lobes are on the same plane.
