> Solution (1) 5.3 cm (2) 6.7 cm Steps of construction: 1. Draw line segment CD=6.7 cm 2. With C as centre and radius more than half of CD, mark two arcs, one above and other below the line CD. 3. With D as centre and same radius, draw two arcs cutting the previous drawn arcs and name the point of intersection as A and B. 4. Join AB and name the point where this line cuts CD as point Q. AB is the perpendicular bisector of CD. (3) 3.8 cm Steps of construction: 1. Draw line segment XY=3.8 cm. 2. With X as centre and radius more than half of XY, mark two arcs, one above and other below the line XY. 3. With Y as centre and same radius, draw two arcs cutting the previous drawn arcs and name the point of intersection as A and B. 4. Join AB and name the point where this line cuts XY as point R. AB is the perpendicular bisector of XY. Mathematics Mathematics (Solutions) Standard VII Suggest Corrections |
