@toheedshafique8971 2 ай бұрын

how did you know for the last example that the angle at the circumference was double that at the centre was applied to angle CAB and not ABC?

@1stClassMaths 2 ай бұрын

The angle at the centre and circumference must start and end at the same points. COB and CAB both start at C and end at B so they come from the chord CB. Angle ABC however comes from the chord AC.

8:07 The way I used is slightly simpler. ACD = CAD = 35º ADC = 180º - ACD - CAD = 110º ADB = 90º BDC = ADC - ADB = 20º BCF = BDC = 20º
