Why does the compass width have to be longer than half when bisecting a segment?
So that the arcs constructed are at midpoint of the line segment to be bisected.
How do you find the midpoint on a number line?
No number lines are infinite in length. If you have a section of the line, a segment, then the midpoint is the average of the lower and the higher value: (L> + H) / 2 (Lower value plus higher value divided by two) Note that if either of the values is less than zero you will have to think a little harder to get the absolute distance between them!
How many line segments can be drawn between two points?
There can only be one line segment between two points. If you only have two points, there's no way to create more than one line from one to the other without adding another point.
What tools are not needed to construct a segment bisector?
A hammer! A pneumatic drill! Anything other than a compass and a straight line (unmarked ruler).
What are Euclid's 5 postulates?
A straight line segment can be drawn by joining any two points.A straight line segment can be extended indefinitely in a straight line.Given a straight line segment, a circle can be drawn using the segment as radius and one endpoint as center.All right angles are congruent.If two lines are drawn which intersect a third in such a way that the sum of the inner angles on one side is less than two right angles, then the two lines inevitably must intersect each other on that side if extended far enough.
