Angles
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
Instructions for students : Read the instructions appearing on the applet carefully in order to know how to proceed on. Practice up to 10 scenarios. 1. Identify the angle of elevation or depression asked in the question 2. Follow up next with measuring the angle by using the clinometer. (Can use this activity after introductory lesson, and prior to a field exercise or project
