Thought-Process to Discover Knowledge

Welcome to nubtrek.

Books and other education websites provide "matter-of-fact" knowledge. Instead, nubtrek provides a thought-process to discover knowledge.

In each of the topic, the outline of the thought-process, for that topic, is provided for learners and educators.

In this page, a short and to-the-point overview of constructing triangles with side-angle-latitude is provided.

To construct a triangle, "side-angle-altitude" are provided. construction of triangle sas Which of the following is required to construct the specified triangle?

  • a scale to mark the given sides
  • a compass to mark angles and sides
  • a ruler, a set-square and a protractor to mark side, parallel, and angle
  • a ruler, a set-square and a protractor to mark side, parallel, and angle

The answer is "a ruler, a set-square and a protractor to mark side, parallel, and angle"

To construct a triangle `/_\ ABC` with given "side-angle-altitude" `4`cm, `70^@`, and `5`cm.construction of triangle sal  •  Construct a line and mark side `bar(AB)` with a compass measuring `6`cm

 •  measure `70^@` angle and draw a ray from point `A`

 •  The objective is to draw a parallel at given `5`cm distance. To achieve this, draw a perpendicular bi-sector for `bar(AB)` and from point `D` mark point `E` at `5`cm. Construct a parallel to on `bar(AB)` point `E`

 •  the parallel and the ray cut at point `C`. Connect the point to point `B` to get `bar(BC)`

`/_\ ABC` is constructed.

Construction of SAL triangle : construction of triangle sal Use a ruler, protractor, a compass, and a set-square to mark side, angle and parallel. Once the vertices are marked, join them to form the triangle.
