Respuesta :

we know that

"Bisect" means to divide into two equal parts

so

If the ray CE is the angle bisector of ADC

then

[tex]Angle(ACD)=Angle(ACE)+Angle(ECD)[/tex]

[tex]Angle(ACE)=Angle(ECD)[/tex]

so

[tex]Angle(ACD)=2Angle(ACE)[/tex]

[tex]Angle(ACE)=\frac{1}{2} Angle(ACD)[/tex]

therefore

the answer is the option

[tex]Angle(ACE)=\frac{1}{2} Angle(ACD)[/tex]

or

[tex]Angle(ACE)=Angle(ECD)[/tex]

Answer: The answer is option C, <ACE = <DCB
