1.Geometrical Constructions / 7 th /Mathematics


  Practice  Set 1  |  Q  1.1  | Page  2

 Draw  the  line  segment  of the  length given  below  and draw  their  perpendicular bisectors.

5.3  cm





 

 

Solution: Step  of construction:

1.  Draw line  segment  AB  = 5.3  cm.

2.  With  A  as center  and  radius  more  than  half  of  AB,  mark two  arcs,  one  above  and other  below the  line  AB.

 3.  With  B  as a  centre  and  same  radius,  draw two  arcs cutting  the  previous drawn  arcs and  name  the  point  of  intersection  as  X  and  Y.

4.  Join  XY  and  na me  the  point  where this line  cuts  AB  as  point  P.  XY  is the perpendicular  bisector  of  AB.

 

Practice  Set 1  |  Q  1.2  | Page  2 Draw  the  line  segment  of the  length given  below  and draw  their  perpendicular bisectors. 6.7  cm

 


Steps  of construction:

1.  Draw line  segment  CD  = 6.7  cm.

2.  With  C as  center and  radius  more  than  half  of  CD,  mark two  arcs,  one  above  and other  below the  line  CD.

3.  With  D as  a  centre  and  same  radius,  draw two  arcs c and  name  the  point  of  intersection  as  A  and  B. utting  the  previous drawn  arcs

 4.  Join  AB  and  name  the  point  where this line  cuts  CD  as  point  Q. perpendicular  bisector  of  CD.

 

 

Practice  Set 1  |  Q  1.3  | Page  2 AB

Draw  the  line  segment  of the  length given  below  and draw  their  perpendicular bisectors. 3.8  cm

Solution: Step s  of construction:

 


1.     Draw line  segment  XY  = 3.8  cm.

2.     2.  With  X  as center  and  radius  more  than  half  of  XY,  mark two  arcs,  one  above  and other  below the  line  XY.

 

Practice  Set 2  |  Q  1.2  | Page  4

Draw  triangle  with the  measures  given In  ∆ STU, Solution: l(ST)  = 7  cm, l(TU) =  4  cm,

 


 

Steps  of construction:

 1.  Draw a  line  ST =  7  cm below. l(SU)  = 5  cm

2.  With  S  as centre  and  5  cm  as  the  radius,  draw an  arc  above  the  line  ST.

3.  With  T  as the  center  and  4  cm  as  the  radius,  draw an  arc cutting  the  previous  drawn arc at  point  U. 4.  Join  US  and  UT. ∆STU is thus the  required  triang le.

 

 

 

Practice  Set 2  |  Q  1.3  | Page  4

Draw  triangle  with the  measures  given In  ∆ PQR, l(PQ) =  6  cm, l(QR) =  3.8  cm, below. l(PR)  = 4.5  cm

 

Solution: Steps  of construction:

1.  Draw a  line  PQ  = 6  cm

 2.  With  P  as centre  and  4.5  cm as the  radius,  draw an  arc above  the  line  PQ.

3.  With  Q  as the  center and  3.8  cm as the  radius,  draw  an  arc cutting drawn  arc at  point  R.

4.  Join  RP  and  RQ. ΔPQR is thus the  required  triangle.

 

  

 Practice  Set 2  |  Q  2  |  Page 4

Draw an  equilateral triangle  with  side  6.5  cm

 

 1.  Draw a  line  BC =  6.5  cm.

2.  With  B  as a  centre  and  6.5  cm  as  radius,  draw an  arc above  the  line  BC.

3.  With  C as  a  centre  and  6.5  cm  as  radius,  draw an  arc cutting  the  previous drawn  arc.

 Name  the  point  of  intersection  as point  A. Join  AB  and  AC. ABC is the  required  equilateral .
