Using Triangles in Maths & Science

We often show pupils to use triangles to solve problems in maths and science classic example being D/ST. Why not teach your pupilshow to construct triangles independently for any x/y relationship? Then they can confidently solve a huge range of problems from first principles, with very few errors?
That’s the thinking behind this resource, which is limited and predominantly aimed at [F] type students. Get the pupils to actually think about what the units are, and construct a triangle based on that, because then they can do it for any similar question, and that will cover many, many maths and science questions. Instead of them just memorising three or four separate triangles, they can insteadunderstandhow to make their own. . It could be extended to Chemistry A Level particularly usefully as well - and also used to discuss unitary analysis as a means of checking the potential validity of answers
