AB is a chord angle made by chord in segment i.e. ∠ACB and angle between chord and tangent i.e. ∠BAQ are equal. 13.Alternate segment theorem 14.Tangents drawn from same points make equal angle at centre. 15.If two chords of AB and CD of a circles cuts each other internally or externally at any points E then 16.If PB is a secant that cuts circle at point A, B and PT is a tangent that touches the circle at T Mathematics By Ambuj singh,ASCENT CLASSES ,Dr Mukherjee nagar New Delhi ssc maths Bank po maths cds maths railways exam maths csat maths cds math cat math quantatative apptitude
