# CONSTRUCTION

CONTENT

1. Construction of Parallel Lines and Perpendicular Lines
2. Bisection of a Given Line Segment
3. Construction of Angles $$90$$ and $$60$$ Degrees

## Construction

To construct a figure in geometry implies drawing it accurately. The proper use of measuring and drawing instruments such as a protractor, ruler, sets square, pencil, etc will enhance accurate construction.

NOTE:

1. Always make a rough sketch of what you are going to draw before starting construction questions.
2. The teacher should introduce all the instruments of geometric construction to the students and students should be able to identify each and know their uses.

## Construction of Parallel Lines

Parallel lines are lines that do not meet. They always have the same distance apart and are in the same direction.

Examples:

1. Construct accurately a line through $$O$$ so that it is parallel to line $$MN$$.

Solution:

(a) Place one edge of the set square along the given line (i.e.
