This is a group lab that I did in my Math 10 class to practice trigonometry skills. The goal was to find the height of a flagpole at our school, by measuring the distance on the ground to the flagpole as well as the angle of elevation. We used a trundle wheel to measure the distance, a clinometer to measure the angle, and a meterstick to measure the height of our eyes.

My group found that the flagpole was 10.95 metres tall. This activity taught me that trigonometry is really useful, and an easy way to measure the height of very tall objects, once you learn how to properly measure and make calculations. I really enjoyed this lab because it was a real-life example, and a great way to practice trigonometry.

Here are some pictures of what we did:
