Question

a line that divides the vertex angle of a triangle in half is called the angle bisector.
○ false
○ true

Explanation:

By the definition of an angle bisector in geometry, a line (or ray) that divides an angle into two equal angles is called an angle bisector. For a triangle's vertex angle, the angle bisector of that angle will split it into two equal parts. So the statement is correct.

Answer:

True
