Answer:
A.Acute angle
Step-by-step explanation:
We are given that an obtuse angle
We have to find that which type of angle of bisector of an obtuse angle.
Bisector of an obtuse angle means it is divided into two equal parts.
Obtuse angle is that angle whose measurement is greater than 90 degrees and less than 180 degrees.
Suppose, we have an obtuse angle =100 degrees
After bisection , it divides into two equal parts
Let x and x are two equal parts of given obtuse angle
[tex]x+x=100[/tex]
[tex]2x=100[/tex]
[tex]x=\frac{100}{2}=50[/tex]
Each angle measurement=50 degrees < 90 degrees
The angle which is less than 90 degrees and greater than zero degrees is called acute angle.
Hence, the bisector of an obtuse angle forms acute angles.
