Each student was subjected to clinicalexamination and digital true lateral cephalometric radiograph. The radiographs were analyzed using AutoCAD 2007computer program to measure the angular and linear variables. Descriptive statistics were obtained for themeasurements for both genders and total sample; independent samples t-test was performed to evaluate thegender difference and Pearson's correlation coefficient test used to detect the relation between the Beta angle andother measurements.Results and Conclusions: The value of Beta angle in this study was 32.63°± 2.57°. When the Beta angle is less than 27°,the case is class II and when it is more than 38°, the case is class III. There is no genders difference regarding the Betaangle and this angle correlated significantly and positively with the mandibular length and articular angle andnegatively with ANB and saddle angles
