The [in]clinometer give angles in the vertical plane so when those are combined with other measurements of azimuth angle and distances, may be used to calculate the dimensions not physically accessible for direct measurement. Since we've obtained angles and lengths we need trig. to do the sums.
clinometer
Superficially.
a clinometer is used to measure the height of an object such as a tree
clinometer is the device which measures angle w.r.t to gravity
because i said they do !
Determine how tall a building, flagpole, street light or basketball goal is. They need to understand basic trig, and angle of elevation/depression. They would need to make a clinometer or hypsometer.
Its trigonometry. Tessellations are shapes.
distance
The Clinometer was invented in 1927 by Charles Lindberg. This device is used to measure angles of slope, elevation, and depression.
The clinometer was invented by William B. Melick in 1889. It is an optical device that is used to measure slopes and angles.
They both deal in the properties of triangles
