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 ba...
TO DIVIDE A STRAIGHT LINE INTO A GIVEN PROPORTION/NUMBER OF EQUAL PARTS 1. Draw a given line “AB” of measurement 2. Draw line “AC” at an angle to “AB” 3. Mark out the required number of equal parts on line ”AC” 4. Join the last number/point marked on “AC” to “AB” 5. Repeat with parallel lines on the other numbers/points marked
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).
