It is found through analysis of the V and B light curves of the UZ Cyg, VW Cyg and AQ Peg Algol-type eclipsing binaries by the Wilson and Devinney (1971) model that all are semi-attached systems, with A-type primary components and K-type evolved secondary which fill the corresponding lobe. Only VW Cyg may alternatively be considered an sd-d system. The computing procedures employed have been described by Maceroni et al, (1981) and Milano et al (1981b).
