1) A working model of theodolite can be made.

A theodolite is an instrument used for determining the horizontal and vertical angles between two points.  It is a key tool in surveying and engineering work, particularly on inaccessible ground.

If the distance between two point in a triangle is known, and two angles are measured using the theodolite, each dimension of the triangle can be determined using the triangulation process.

 

2) A working model of clinometer can be made.

A clinometer is a fairly simple instrument which is used to measure the angle of a slope. By using the principles of trigonometry, the height of tall objects can be calculated from the angles measured.
