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 angle-side-angle (a side between given 2 angles) is provided.

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

• 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 to mark parallel lines and angle

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

To construct a triangle /_\ ABC with given "angle-side-angle" 70^@, 6cm, and 50^@  •  Construct a line and mark side bar(AB) with a compass measuring 6cm

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

•  measure 50^@ angle and draw a ray from point B

•  the two rays cut at point C.

/_\ ABC is constructed.

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