Answers
Given : 3 circles each with radius 2cm
To Find : Divide the first circle into 2 equal parts,
the second circle into 6 equal parts and
the third circle into 8 equal parts.
Solution:
Take a point O
Using compass width = 2 cm Draw circle
Repeat this process 3 times to get 3 circles
Divide the first circle into 2 equal parts,
Take a point A on circle
Draw a line segment starting from A and passing through O and meeting circle at B
AOB Divides circle in two Equal parts
the second circle into 6 equal parts
Take a point A on circle
Keeping compass width same and taking A as center take a point B on circle
Then Keeping compass width same and taking B as center take a point C on circle then point D , E , F
Join AD , BE & CF
the third circle into 8 equal parts.
Take a point A on circle
Draw a line segment starting from A and passing through O and meeting circle at B
Draw a line perpendicular at O an AB meeting circle at C & D
Then Draw angle bisector of AOC & AOD
