(a) A transverse is a series of connected straight lines whose lengths and bearings are measured. An open transverse starts from one end oF a particular road or path to another (See diagram below). It is transverse, i.e. straight line that doesn't close at the point of origin.
Line | Length (mm) | Length (cm) | Bearing |
AB | 370m | 7.4cm | |
BC | 450m | 6.5cm | |
CD | 265m | 5.3cm | |
DE | 560m | 11.0cm | |
EA | 140m | 2.8cm | |
Use the data above to: (i) plot the area of the compound on a scale of 1 cm to 50m.
(ii) find the direct distance between D and A, in metres = 12.6cm. Scale = lcm to 50m (1:5,000) 12.7cm = 12.7 x 50 = 635m
Scale: 1:5000 (1cm to 50m)
