How do you construct a perpendicular line segment?

23
Construct: a line through P perpendicular togivenline.
1. STEPS:
2. Place your compass point on P and swing an arc of any sizethatcrosses the line twice.
3. Place the compass point on one of the two locations wherethearc crossed the line and make a small arc belowtheline (on the side where P is not located).

Also, how do you construct a perpendicular bisector of a segment?

The perpendicular bisector of a line segment

1. open the compass more than half of the distance between A andB,and scribe arcs of the same radius centered at A and B.
2. Call the two points where these two arcs meet C and D. Drawtheline between C and D.
3. CD is the perpendicular bisector of the line segment AB.
4. Proof.

Also Know, how do you copy a line segment? Start with a line segment PQ that wewillcopy. Mark a point R that will be one endpoint of thenewline segment. Set the compasses' point on the point P oftheline segment to be copied. Adjust thecompasses'width to the point Q. The compasses' width is now equalto thelength of the line segment PQ.

Additionally, how many perpendicular bisectors can be constructed for a line segment?

For every line segment, there isoneperpendicular bisector that passes through themidpoint.There are infinitely many bisectors, but onlyoneperpendicular bisector for anysegment.

How do you construct a perpendicular line with a compass?

Steps

1. Draw one of the lines and mark two points on it.
2. Set a compass to at least half the distance between thetwopoints.
3. Use the compass to draw a circle centered around each point.Thecircles should intersect in two points on opposite sides oftheline.
4. Draw a line through the two points of intersection.

How do you construct a bisector?

Method 2 Constructing a Bisector withaCompass
1. Draw an arc across both rays. Open the compass to any width,andplace the point of the compass at the angle's vertex.
2. Draw an interior arc.
3. Draw a second interior arc intersecting the firstinteriorarc.
4. Draw a line from the vertex to the point where thearcsintersect.

What is a perpendicular line?

In elementary geometry, the property ofbeingperpendicular (perpendicularity) is the relationshipbetweentwo lines which meet at a right angle (90 degrees).Aline is said to be perpendicular toanotherline if the two lines intersect at arightangle.

What is the meaning of bisector?

A bisector is something that cuts an objectintotwo equal parts. It is applied to angles and line segments. Inverbform, we say that it bisects the other object.

What is the first step in the construction of a perpendicular line from point P to line M?

To draw a perpendicular from the point Ptothe line m, the first step should be mark andarc.Take a compass and place it on the point P and then markasmall arc right below the line m. After you have markedanarc below the line m, take a straightedge and carefullyjointhe point P to that arc and draw aline.

What is bisector of a line segment?

In general 'to bisect' something means to cut it intotwoequal parts. The 'bisector' is the thing doing thecutting.With a line bisector, we are cutting a linesegmentinto two equal lengths with another line -thebisector. If AB crosses at a right angle, it is calledthe"perpendicular bisector" of PQ.
