Mathematics Video Lesson: Constructing Triangles (Set 1)

61 comments:

  1. Special message for my dear students from 2E & 2F (2NT E-learning):

    I once said in my Maths lesson that in constructing triangles, this was one of the rules you must remember:

    Rule: "You must always start drawing the LONGEST side first."

    Please answer these questions:

    Q1: Can we ALWAYS apply this rule?

    Q2: Give an example of a case when this rule does NOT apply.
