Using trigonometry for heights and distances: angles of elevation and depression, and bearings.

Learn

  1. 1Angles of elevation and depressionMeasure from the horizontal, spot that elevation and depression are equal, and handle eye height, two angles, ladders and shadows.Done20 min
  2. 2BearingsMeasure clockwise from north at the right point, write three figures, find back bearings, read compass directions like N 40° E, and split a journey into north and east parts.Done18 min
  3. 3Drawing the bearing diagramThe step that decides most bearing questions: turn the words into a diagram, one sentence at a time, then find the angle inside the triangle.Done15 min
