What is the third step of the​ construction?

A. With the same compass​ setting, put the compass point on one of the endpoints of PS and draw an arc.
B. Add another ray starting from point T​ (or R) to the ray in the first step. Make sure to use an arc created with the same compass setting.
C.With the same compass​ setting, put the compass point on the endpoint of the construction in the first step and draw an arc that intersects the ray.
D.Add another ray starting from point P​ (or S) to the ray in the first step. Make sure to use an arc created with the same compass setting.

What is the fourth step of the​ construction?
A. Open the compass to the length of TR.
B. Open the compass to the length of PS.
C. Open the compass to the length of TS.
D. Open the compass to the length of the construction created in the previous step.

What is the final step of the​ construction?

A. With the compass setting from the previous​ step, place the compass at the intersection of the arc drawn in the third step and the ray with endpoint D​ (or E). Draw another arc that intersects the ray on the side of the ray opposite the endpoint. Label this new intersection E​ (or D).
B. With the compass setting from the previous​ step, place the compass at the endpoint of the ray with endpoint T​ (or S). Draw another arc to create an opposite ray. Draw this opposite ray and name its intersection with the created arc E​ (or D).
C. With the compass setting from the previous​ step, place the compass at the endpoint of the ray with endpoint D​ (or E). Draw another arc to create an opposite ray. Draw this opposite ray and name its intersection with the created arc E​ (or D).
D. Place the compass at the intersection of the arc drawn in the previous step and the ray with endpoint T​ (or S). Draw another arc that intersects the ray on the side of the ray opposite the endpoint. Label this new intersection E​ (or D).
