Question

Draw a line 7 Centimetres long and from each end point, draw upright lines, both 4 centimetres high. draw a line joining the top ends of these lines.
Measure its length.
Look at the figure you got. Isn't it a rectangle? What are its length and breadths?
Here are some things of rectangular shape:

Answer 1

Answer:

Bisect a line of length 7 cm. Write down the steps of construction.

Step-by-step explanation:

Steps of construction :

1) Draw a line segment AB = 7 cm by using a graduated ruler.

2) With A as centre and radius more than half of AB, draw arcs, one on each side of AB.

3) With B as centre and the same radius as in step 2, draw arcs cutting the arcs drawn in step 2 at E and F respectively.

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=MB = 3.5 cm
