Which of the following is a step in bisecting a line segment?
1 answer:
Answer:
c. Use a compass to swing an arc on either side of the segment for each endpoint.
Step-by-step explanation:
The steps to constructing a perpendicular bisector are illustrated in the attachment.
Steps 2 and 3 are described by answer choice C.
__
<em>Other choices</em>
(a) In order to get the arcs to intersect each other, their radius must be <em>more than</em> one half of the segment length.
(b) At no point in the construction are concentric circles involved.
(c) A ruler is not used in any <em>construction</em>. Only a straightedge with no markings will be used for construction.

Step-by-step explanation:
We have got the lines :
Both lines intercept the x-axis in the point :
In all point from x-axis the y-component is equal to 0.
We replace the I point in the lines equations:
From the first equation :
From the second equation :
Then
Finally :
y = ax + b and y = cx + d have the same x-intercept ⇔ad=bc
