Maths @ Kurunjang

On Friday the 18th of May, my class, 9C2, had another chance to participate in interactive and investigative learning in the form of finding and studying right angled triangles in the courtyard. Before going out, Mr Ronalds explained to the class the difference between angles of elevation and angles of depression. We then moved outside and formed small groups of 3 or 4. Our task was to find right angled triangles around the courtyard, such as ramps or simply using a clinometer to measure the angle of elevation/depression of an object. After finding triangles, we measured one or two of the lengths and then used trigonometry to find an angle within or find the height of an object. This activity was very helpful and also a fun way to consolidate and improve our Trig skills.
