(i)
(A) Given : Line segment AB = 8 cm.
(B) To Draw : Bisector of line segment AB.
(C) To Find : Measurement of each part.
Drawing :
(1) Draw a line segment AB = 8 cm.
(2) Now, open the compass more than half and cut an arc on both sides letting A and B as center, which intersects each other at points C and D.
(3) Draw a line CD, joining the points C and D, which cut AB at point O. ∴ OA and OB are two required segments of equal lengths.
Measurement :
OA = OB = 4 cm.
(ii)
(A) Given : Line segment AB = 7.6 cm.
(B) To Draw : Bisector of line segment AB.
(C) To Find : Measurement of each part.
Drawing :
(1) Draw a line segment AB = 7.6 cm.
(2) Now, open the compass more than half and cut on arc on both sides, letting A and B as center, which intersects each other at point C and D.
(3) Draw a line CD, joining the points C and D, which cut AB at point O. ∴ OA and OB are two required segments of equal lengths. Measurement : OA = OB = 3.8 cm.
(iii)
(A) Given : Line segment AB = 5.8 cm
(B) To Draw : Bisector of line segment AB.
(C) To Find : Measurement of each part.
Drawing :
(1) Draw line segment AB = 5.8 cm
(2) Now, open the con pass more than hall and cut an arc on both sides letting A and B as center, which intersects each other at point C and D.
(3) Draw a line CD, joining the points C and D, which cut AB at point O. ∴ OA and OB are two required segments of equal lengths.
Measurement :
OA = OB = 2.9 cm
(iv)
(A) Given : Line segment AB = 6.4 cm.
(B) To Draw : Bisector of line segment AB.
(C) To Find : Measurement of each part.
Drawing :
(1) Draw a line segment AB = 6.4 cm.
(2) Now, open the compass more than 6.4 cm halt and cut an arc A on both sides, letting A and B as center, which intersects each other at point C and D.
(3) Draw a line CD, joining the points C and D, which cut AB at point O. ∴ OA and OB are two required segments of equal lengths.
Measurement :
OA = OB = 3.2 cm.
