This applet was modified initially from the Clinometer https://www.geogebra.org/material/show/id/jUn7APq2 by sharon_ong
Extended to include a self practice review exercise to identify angles of elevation and depression., and autogenerated scenarios for clinometer measurements for both types of angles.
There is a nice diagram at https://www.geogebra.org/m/Hx2jyapJ on the making a clinometer , by sudheer kumar kotha
