Номер 1 Рассмотрим треугольник AOC и треугольник BOD: угол AOC равен углу BOD(как вертикальные) AO=OB и CO=OD(по условию,т.к. точка серединой является O) значит треугольник AOC равен треугольнику BOD(по двум сторонам и углу между ними) значит угол DAO равен углу CBO(в равных треугольниках против равных сторон лежат равные углы)
номер 2: Рассмотрим треугольник ABD и треугольник ADC: по условию угол BDA равен углу ADC сторона AD-общая и по условию угол BAD=углу DAC(т.к. AD биссектриса) Значит треугольник ABD равен треугольнику ADC(по двум углам и стороне между ними) значит сторона AB=AC(т.к. в равных треугольниках против равных углов лежат равны стороны)

Рассмотрим треугольник AOC и треугольник BOD:
угол AOC равен углу BOD(как вертикальные)
AO=OB и CO=OD(по условию,т.к. точка серединой является O)
значит треугольник AOC равен треугольнику BOD(по двум сторонам и углу между ними)
значит угол DAO равен углу CBO(в равных треугольниках против равных сторон лежат равные углы)
номер 2: Рассмотрим треугольник ABD и треугольник ADC:
по условию угол BDA равен углу ADC
сторона AD-общая
и по условию угол BAD=углу DAC(т.к. AD биссектриса)
Значит треугольник ABD равен треугольнику ADC(по двум углам и стороне между ними)
значит сторона AB=AC(т.к. в равных треугольниках против равных углов лежат равны стороны)
