Measuring Height of Object-Sun and Shadow-Similar Triangles
This app is used to exemplify how to indirectly calculate the height of an object out in the sun, using similar triangles principles.
You may adjust the Height of the objects and the Angle of the sun, until the figure will follow according to the data you have collected:
1. Adjust the height of the object you know it's height (the red line).
2. Adjust the angle of the sun, so that the shadow of that object will be the same as you've collected.
3. Adjust the height of the object you don't know it's height (the Green line), so that it's shadow will reach that you've measured.
