Problem 117:
Given a point $B$, a point $C$ and a point $T_{c}$, construct the triangle ABC.

Construction: 
1. Using the point $B$ and the point $C$, construct a line $a$ (rule W02);
2. Using the point $B$ and the point $T_{c}$, construct a line $c$ (rule W02);
3. Using the point $T_{c}$ and the line $a$, construct a circle $k(T_{c},foot[T_{c},b])$ (rule W11);
4. Using the circle $k(T_{c},foot[T_{c},b])$, the point $C$, the point $T_{c}$ and the line $a$, construct a line $b$ (rule W13);
5. Using the line $b$ and the line $c$, construct a point $A$ (rule W03);
6. Using the point $B$ and the point $C$ construct the line $\_a$ (rule W02);
7. Using the point $A$ and the point $C$ construct the line $\_b$ (rule W02);
8. Using the point $A$, the point $C$ and the point $B$ and the line $\_b$ and the line $\_a$ construct the angle bisector $\_s_{c}$ (rule W17);
9. Using the point $A$ and the point $B$ construct the line $\_c$ (rule W02);
10. Using the line $\_s_{c}$ and the line $\_c$ construct the point $\_T_{c}$ (rule W03);

Statement:
Prove that the point $B$ is identical to the point $B$.
