You would need to be familiar with the formulas in geometry. You can see how to solve geometry word problems in the following examples: Problems involving Perimeter Problems involving Area Problems involving Angles There is also an example of a geometry word problem that uses similar triangles.
Writing an equation and finding the dimensions of a rectangle knowing the perimeter and some information about the about the length and width.
Over the years the courses evolved to the point where they focused less on heuristics per se and more on introducing students to fundamental ideas: the importance of mathematical reasoning and proof..., for example, and of sustained mathematical investigations (where my problems served as starting points for serious explorations, rather than tasks to be completed).
Schoenfeld also suggested that a good problem should be one which can be extended to lead to mathematical explorations and generalisations.
A line in geometry is has most of the same characteristics as it does in real life (and in algebra).
A geometric line is straight, and it extends indefinitely in opposite directions.
A line segment is shown below; the ends of the line segment are shown as points. (Note that the "unit" can be inches, feet, meters, or any other type of length measurement.
If the unit is specified, use that particular unit; otherwise, the generic term "units" is sufficient.)square (a rectangle whose length and width are equal) with sides of length 1.
This derivation, although not shown in its full mathematical rigor, produces the correct area formula for all triangles, not just the one shown above.
