To Construct an Angle Equal to a Given Angle
In order to construct an angle equal to a given angle ABC, we take the following steps:
Step-1: Draw an angle ABC.
Step-2: Draw a ray KJ.
Step-3: With B as centre draw an arc cutting BA and BC at P and Q respectively.
Step-4: With K as centre and the same radius as above, draw an arc cutting KJ at R.
Step-5: With R as centre and radius equal to PQ cut the previous arc at S.
Step-6: Join KS and draw ray KL. Angle LKJ so obtained is the required angle.
Verification: Measure angle ABC and angle LKJ with the help of a protractor. You will find that angle ABC = angle LKJ.
To Bisect a Given Angle
In order to bisect a given angle ABC, we take the following steps:
(i) Draw any angle ABC.
(ii) With B as centre and a suitable radius draw an arc that cuts BA and BC at points M and N respectively.
(iii) With M as centre and radius more than half of MN draw an arc.
(iv) With the same radius and N as centre draw another arc to cut the first arc at R.
(v) Join BR and produce it to form ray BX.
Then ray BX bisects angle ABC
Verification: Measure angle CBX and angle XBA. You will find that angle CBX = angle XBA.
What is the meaning of bisector of angle?
The (interior) bisector of an angle, also called the internal angle bisector, is the line or line segment that divides the angle into two equal parts. The angle bisectors meet at the incenter.
How many angle bisectors are possible in an angle?
An angle only has one bisector. Each point of an angle bisector is equidistant from the sides of the angle. The interior or internal bisector of an angle is the line, half-line, or line segment that divides an angle of less than 180° into two equal angles.
Can a ray be bisected?
A line of reflection must exist so that when the figure is folded along this line, each point on one side of the line maps to a corresponding point on the other side of the line. A ray cannot be bisected.
