1. Given:
![\bar{TO}\cong\bar{AN}](https://img.qammunity.org/2023/formulas/mathematics/college/wb6tlgzd8bhp8w3i3q8fxpi8vyw7mvsbxa.png)
Conclusion: Definition of congruence
Reason:
The line segment TO and AN are equal in length.
2. Given:
E is the midpoint of the line segment BD.
Conclusion: Definition of midpoint
Reason:
Since, E is in equidistant from the proint B and D on the line segment BD.
Therefore, using using the Definition of midpoint, E is the midpoint of the line segment BD.
