Question

true or false, an angle bisector is a ray starting at the vertex of an angle and divides the angle into two obtuse angles

Answer 1

which one do you think it is and why?

Answer 2

This is false. You see, an it's a ray that bisects the vertex, yes, but it doesn't divide them into two obtuse angles. That would mean 280 degrees division. It divides an obtuse angle into two smaller angles e.g., 90 degree angles.
