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...
