BISECTORS AND... KITES?

It is time to get started with the compass! We will draw two VERY IMPORTANT constructions, used in technical drawing to construct almost everything, EVEN A KITE!

It is CRUCIAL that you learn how to do them by observing and practising. SO LETS DO IT!:

PERPENDICULAR BISECTOR LINE

Definition:

The perpendicular bisector is a PERPENDICULAR line that DIVIDES a line segment into TWO EQUAL parts. It also makes a right angle with the line segment. Each point on the perpendicular bisector is at the same distance from each of the endpoints of the original line segment.

It is basically a line which cuts a line segment into two equal parts at 90°.

ANGLE BISECTOR LINE

Definition: 

It is a line that DIVIDES the angle in TWO EQUAL parts.
