We present a detailed light curve analysis of three eclipsing binaries, consisted of two Algol type systems, SY Sge and V688 Aql, and one W UMa type system, CY Ari, observed at the Ankara University Observatory. The light curves constructed in Johnson BVRI pass-bands were simultaneously analysed on the basis of Roche Geometry. Fourier coefficients method was applied on the light curve of W UMa type system to estimate a set of initial system parameters. Moreover, since there is not any radial velocity measurement of the systems, a q-search test was applied for all three systems to reach a minimized $\chi^2$. Combining system parameters with photometric mass ratio allows us to obtain absolute parameters of the systems which leads to locate the systems on theoretical HR diagram and to estimate their evolutionary status.
