6. Compound curve consists of two or more _____ simple curves having _____radius.
7. In a compound curve, the point of the common tangent where the two curves join is called the _____
8. A reverse curve is formed by two circular simple curves having a _____ but lies on opposite sides.
9. At the point where the curve reversed in its direction is called the _____
10. If the line of sight is rotated about the vertical axis until horizontal circle reading becomes _____, this line of sight falls on the _____.
11. What are the four types of reversed curves?

Problem:

A reversed curve has a radius of curve passing through the P.C equal to 200m and that of the second curve passing through the P.T is 460m long. If the central angle of curve is 12 degrees;

• Find the perpendicular distance between the two parallel tangents.
• If the stationing of P.C. is 2 + 360.20, find the stationing of the P.R.C.
• Find the stationing of the P.T.
