Transcribed Image Text:**Construct Viable Arguments: Use the Diagram Shown**
The diagram includes a point \( T \), from which two rays \( \overrightarrow{TA} \) and \( \overrightarrow{TB} \) extend. There is a third ray \( \overrightarrow{TC} \) that appears to be bisecting the angle \( \angle ATB \). The segments are labeled as follows: the angle \( \angle ATB \) is divided into two angles, 1 and 2, by ray \( \overrightarrow{TC} \).
### Exercises:
**Write a statement that can be justified by each of the following:**
a. **Definition of angle bisector**
b. **Angle Addition Postulate**
Note: The angle bisector is a ray that divides an angle into two equal smaller angles. The Angle Addition Postulate states that if a point lies inside an angle, the sum of the two adjacent angles created is equal to the original angle.
