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.

Which of the following property helps to copy an angle using compass?

• two triangles with identical sides have identical angles
• two triangles with identical sides have identical angles
• no property of triangle can be used to copy an angle

The answer is "two triangles with identical sides have identical angles"

Given /_ BAC. To copy this angle, make a triangle of random sides /_\ APQ. Copy the length of line segment bar(AQ) to mark point L on the given line. Copy the lengths of line segments bar(AP) and bar(QP) to mark M from points X and L respectively. Join the points X and M. The angle /_BAC is reproduced in /_LXM.

Copying a Given Angle : Mark a triangle in the given angle and reproduce the sides of a triangle which copies the angle.
