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-side (angle between given two sides) is provided.

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

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

The answer is "a protractor and compass+scale to mark angles and sides"

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

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

 •  measure `bar(AC)` `4`cm in a compass and draw an arc cutting the ray

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

`/_\ ABC` is constructed.

Construction of SAS triangle : construction of triangle sas use compass to the measure lengths and protractor to measure the given angle. Once the vertices are marked, join them to form the triangle.
