Constructing Parallel and Perpendicular Lines

The video tutorial teaches how to construct parallel and perpendicular lines using a ruler and set square. It covers the steps to create parallel lines at specific distances and perpendicular lines both on and outside a given line. The tutorial concludes by encouraging students to practice these constructions on their own.

What is the primary focus of the video tutorial?

• Construction of parallel and perpendicular lines

• Measurement of angles

• Drawing circles

• Construction of triangles

What tools are used to construct parallel lines?
