1. Instructions
a. Look carefully at the location where we will practice.
b. Note carefully the work sheet and measures work.
c. Yalon target should be at two positions / sides (right and kin).
d. Plugging yalon must be upright (not always perpendicular to the ground).
e. Installation yalon-yalon must exactly match the points that have been determined.
f. Creating employment report
2. Equipment and Supplies Used
1. Yalon (at least 8 pieces)
2. Stakes wood / bamboo while (at least 4 pieces)
3. Tape measure / meter (minimum 15 m) 4. Alas stationery, Stationery writing, paper to sketch / note.
3. Safety
There are several things to note in the work so that safety is assured, among others:
a. When carrying yalon, draped, front blunt, and should not be dragged yalon
b. Currently, the practice is prohibited kidding.
c. Be careful when plugging yalon to the ground.
d. After completion of the practice, the equipment must be cleaned again.
How I Work 4.Langkah
a. Plug yalon at point P and point Q (P and Q the main point).
b. Step yalon R so that it can look into P and Q.
c. Measure PR and QR.
d. For PR into parts the same as (4 parts), so RS = 1/4 RP.
e. For RQ into parts the same as (4 parts), so the RQ RT = 1/4.
f. Connect and renew ST, ST now // PQ.
g. Projecting the point P to the extension of TS in A, so the PA perpendicular ST (using a mirror angle / penta prism or by means of a high line, tall isosceles triangles, (base divided by 2 as point A)
h. Q also projected extension to ST in D, such that DQ = AP, and DQ perpendicular DT
i. Define the points divisor B, C taste for BB ‘// DD’ by comparison triangle = 3: 4: 5 and set point B ‘with a measuring BB’ = AP.
j. With the same way for CC ‘// DQ, CC’ = DQ
k. Thus point B, S, T, C aligned with the line PQ.
l. Do it for the points S ‘T’ then connect point – the point PB ‘S’ and QT ‘and C’, which is an unobstructed line PQ building
Method II:
In the second way, made a parallel with another straight gris PQ.pilihlah point A and point B such that the distance from the PQ and AB equal length = p. Thus, it should be made <PAB = <QBA both 90o. How right angle is made? Define the points a, b, c, d, and then in a straight line AB and make these points on the high line, the line is made equal to the distance P. Then the obtained points a1, b1, c1, d1, and so that the points on the straight line PQ.
