TO BISECT A GIVEN LINE


 

 

TO BISECT A GIVEN LINE

BISECTING A GIVEN LINE (A,B).

GUIDELINES:



1.     Draw line A,B with the measurement given.

 

2.     Make A the center and using any radius greater than half the length of AB, draw an arc above and below the given line AB.

 





3.     Make B the center, using the same radius, draw an arc to cut the previous one drawn above and below.

 



4.     Now join the points of intersection of the arcs above cutting through the given line below.

 

 



 

 

5.     Now you have bisected line AB, that gives you an equal half of the given line.

  TO CONSTRUCT AND DRAW ANY POLYGON GIVEN THE LENGTH OF ONE SIDE/BASE GUIDELINES : 1.   1.   Draw the length of the given base “AB”.     2.     Bisect the line.   3.     Construct a square on base “AB”.   4.     Draw a diagonal in the square and label “4” to cut the bisector of “AB”.   5.     With center “B” and radius same as base/length of square, draw an arc cutting the bisector of “AB”, label arc intersecting at bisector “AB” “6”. 6.     Bisect “4 and 6” to get point 5 (on the vertical bisector).           7.     Take unit measurement (using divider/compass) of 4-5/5-6 and mark out the remaining points, 7, 8, 9, 10…   8.     TO DRAW A PENTAGON a.      Take 5 as center and radius 5B or 5A and draw a circle. b.     Use base measurement AB and mark off round the circle.   c.      Join the marked off points to form a pentagon.     9.     TO DRAW A HEXAGON a.      Take 6 as center and radius “6B” or “6A” and draw a

TO CONSTRUCT A PERPENDICULAR LINE AT A GIVEN POINT

Image
  TO CONSTRUCT A PERPENDICULAR LINE AT A GIVEN POINT 1.        Draw line AB with the given measurement     2.     Mark the given point “C”   3.     Making “C” the center and taking radius of your choice, draw semi-circle “D E”     4.     Taking center “D” and “E”, and radius greater than the radius of the semi-circle, draw an arc with point “D” and “E” to intersect at “F”     5.     Join the point of intersection at “F” with “C” to form a perpendicular line to “AB”     NB: the arcs and semi-circles are drawn using thin/faint lines, while the outlines are ”AB” and “FC”(Thick lines).
