It then applies angle rules with parallel lines, straight line angles adding to 180 degrees, triangle angle sums, and a right angle triangle using sine to find a length. Other sections cover scaling grass seed for rectangles, comparing festival areas and area per person, converting square centimetres to square metres, and finding grass seed area made from rectangles, a triangle, and a quarter circle for bag cost. The video also includes cylinder volume and fertilizer mixing across four tanks, and finishes with similar triangles and an angle proof for an isosceles triangle.
