Perpendicular bisector is a line that divides a provided line segment exactly into two halves developing 90 degrees at the intersection point. Perpendicular bisector passes through the midpoint of a heat segment. It can be built using a ruler and a compass. It makes 90° top top both political parties of the line segment the is being bisected.

A perpendicular bisector is identified as a heat or a line segment that divides a provided line segment into two components of same measurement. 'Bisect' is the term provided to define dividing equally. Perpendicular bisectors intersect the heat segment the they bisect and make four angles that 90° every on both sides. Perpendicular means a heat or a heat segment make an angle of 90° with one more line or heat segment. In the figure displayed below, the perpendicular bisector bisects the heat segment abdominal muscle into two equal halves.


Perpendicular bisector top top a line segment have the right to be created easily making use of a ruler and a compass. The created perpendicular bisector divides the offered line segment into two same parts exactly at the midpoint and also makes two congruent heat segments.

Steps for building Perpendicular Bisector

Follow the steps below to build a perpendicular bisector that a heat segment.

Step 1: attract a line segment XY the any suitable length.Step 2: take it a compass, and also with X as the center and with an ext than fifty percent of the line segment XY together width, draw arcs over and listed below the line segment.Step 3: Repeat the very same step with Y as the center.Step 4: label the point out of intersection as 'P' and 'Q'.Step 5: join the clues 'P' and 'Q'. The allude at i m sorry the perpendicular bisector intersects the heat segment XY is that is midpoint. Label it together 'O'.


Perpendicular bisector that a triangle is thought about to it is in a line segment the bisects the political parties of a triangle and are perpendicular to the sides. The is not necessary that they need to pass through the peak of a triangle however passes with the midpoint that the sides. The perpendicular bisector of the sides of the triangle is perpendicular at the midpoint the the political parties of the triangle. The allude at which every the 3 perpendicular bisectors satisfy is dubbed the circumcenter of the triangle. There deserve to be three perpendicular bisectors for a triangle (one because that each side). The measures of building and construction of a perpendicular bisector for a triangle are shown below.

Draw a triangle and label the vertices as A, B, and C.With B as the center and much more than half of BC as radius, draw arcs over and below the heat segment, BC. Repeat the same process without a readjust in radius v C together the center.Label the point out of intersection the arcs together X and also Y respectively and also join them. This is the perpendicular bisector for one side of the triangle BC.Repeat the same process for sides abdominal muscle and AC. All the 3 perpendicular bisectors make an angle of 90“ in ~ the midpoint of every side.

The perpendicular bisector that an it is intended triangle after building and construction is shown below.XY, HG, and also PQ room the perpendicular bisectors of sides BC, AC, and abdominal muscle respectively.


Perpendicular bisectors can bisect a line segment or a heat or the political parties of a triangle. The vital properties that a perpendicular bisector are detailed below.

Perpendicular bisector,

Divides a line segment or a line into two congruent segments.Divides the sides of a triangle into congruent parts.They do an angle of 90° v the line the is being bisected.They crossing the heat segment exactly at that midpoint.The point of intersection the the perpendicular bisectors in a triangle is called its circumcenter.In one acute triangle, they accomplish inside a triangle, in one obtuse triangle castle meet external the triangle, and in best triangles, they fulfill at the hypotenuse.Can be only one in number for a provided line segment.

Topics pertained to Perpendicular Bisector

Given below is the list of object that space closely linked to the perpendicular bisector. This topics will additionally give friend a glimpse of just how such concepts are extended in

Example 1: find at which suggest a perpendicular bisector bisects a heat segment of size 10 units.

Solution:A perpendicular bisector is a line that bisects a provided line segment right into two congruent line segments specifically at that is midpoint. The is provided that the heat segment is the the size 10 units. So, the perpendicular bisector bisects the heat segment specifically at 5 units and the line segment of 10 devices is separated into two line segment of 5 units each.

Example 2: have the right to you uncover if the points of intersection of all the perpendicular bisectors because that an obtuse triangle PQR with dimensions as follows: PQ = 5 units, QR = 8 units, and PR = 9 systems lies outside or within the triangle?

Solution: The perpendicular bisector of any kind of triangle bisects the sides at that is midpoint. In a triangle, there room three perpendicular bisectors that deserve to be attracted from each side. To find the perpendicular bisector that a triangle through the offered sides, follow the steps given below.

Draw a heat segment PQ of length 5 units.With P together the center and an ext than half of PQ together radius, attract arcs over and listed below the line segment PQ. Repeat the same process with Q together the center. Sign up with the points of intersection of this arcs.Repeat the same procedure and attract perpendicular bisectors because that the sides QR and also PR.

The construction of the perpendicular bisectors the the obtuse triangle is shown below.


We can plainly see the all the perpendicular bisectors bisect at a allude outside the triangle.

Example 3: attract a perpendicular bisector come the diameter the a circle who radius is 4 units.Solution: Given, the radius the the circle = 4 units. Diameter = 2 × radius. So, diameter = 2 × 4 = 8 units. The measures to build a perpendicular bisector top top a diameter the a circle are as follows.

Draw a line segment XY of size 8 units.Using a compass, with X as the center and the radius as much more than 4 units, draw arcs above and below the heat segment.Repeat the same process with Y as the center. Label the point out of intersection that the arcs together P and also Q.Join the points P and also Q. This line is the perpendicular bisector for the diameter that the circle. Label the point of intersection that the perpendicular bisector with the diameter as O.
