Now, let's think about what other tools we can use to draw the diameter. Let's think about relationship between a chord and a diameter. This relationship can be explained by the Converse Perpendicular Chord Bisector Theorem.
Converse Perpendicular Chord Bisector Theorem
If one chord of a circle is the perpendicular bisector of another chord, then the first chord is a diameter.
We will first draw a chord and find its perpendicular bisector, which is a diameter. To do so, we need a straightedge and a compass. Let's draw a chord on the wood.
The perpendicular bisector of this chord will be the diameter of the circular wood. To draw it, we place the tip of the compass on one of the endpoints of the chord. Then, we open the compass beyond the midpoint, and draw an arc. We then place the tip on the other endpoint and draw another arc. We repeat this procedure for a different amplitude of the compass.
Finally, we draw the line that connects intersection of the arcs drawn.
We have drawn the diameter of the circle. We could use a straightedge and a compass to draw the diameter.
