Up Next in Term 3
This lesson, and the previous lesson on angles and triangles, will be rather helpful in starting the matric sections on Euclidean Geometry. So today, we will go over the properties of different shapes and learn how to prove which shape is which. We will also do a couple of examples so get your pe...
Similarity: triangles and polygons
Today we will investigate what it means for two polygons to be similar. Then we will explain the three methods or conditions used to prove that two triangles are similar, followed by the theorem that equiangular triangles are similar, and we obviously cannot leave out the area of triangles and so...
