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.

Read in the blogs more about the unique learning experience at nubtrek.

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. 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" 4cm, 70^@, and 5cm.  •  Construct a line and mark side bar(AB) with a compass measuring 6cm

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

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