Answer:
an infinite points?? like theres too many do you want an example of a point on there??
Step-by-step explanation:
we know that
the sum of an exterior angle and the adjacent interior angle.of a triangle is equal to 180 degrees, because are supplementary angles
therefore
the answer is the option
An exterior angle is supplementary to the adjacent interior angle.
We are given that ray CE is an angle bisector of angle ACD. With this, we have the equation,
mACE = mECD
Next, we look at the choices
<span>mECD = mECB > This not possible since ray CD is between the two angles
mACE = mACD > This is still not possible since ray CE is between the two angles
mACE = mDCB > This is possible since angles ACE, ECD and DCB are complementary angles.
mECD = mACD > This is not possible since ray CE is between the two rays
The answer is the third option</span><span />
