Draw a line segment of length 8.6 cm. Bisect it and measure the length of each part.
We are given a line segment of length 8.6 cm
We have to bisect it and measure each part.
Now we will follow the following steps of construction.
STEP1: Draw a line segment AB = 8.6 cm by using a graduated ruler.
STEP 2: With A as centre and radius more than half of AB, draw arcs, one on each side of AB.
STEP3: With B as centre and the same radius as in step II, draw arcs cutting the arcs drawn in step II at E and F respectively.
STEP 4: Draw the line segment with E and F as end-points. Suppose it meets AB at M. Then M bisects the line segment AB.
By measuring AM and MB, we find that
AM = MB = 4.3cm
