Question

construct a line segment whose length is thrice the length of ab=3cm​

Answer 1

let the length of given line segment be 1cm.

then thrice of it = 1×3=3cm

Answer 2

Answer:

Given,

A line segment (AB) of length = 3cm.

To Find,

A line thrice the length of AB.

Solution,

We can simply draw a line thrice the length of AB by using a compass.

As we know AB= 3cm.

thrice of AB= 3 × 3cm= 9cm.

Now we have to draw a line segment of length 9cm.

We can do this by following these steps.

• Mark a point C.
• Measure 9cm on the compass using the scale.
• keep one end of the compass at C and mark another point in the direction you want the resultant line segment.
• Name the marked point as D.
• Now join C and D using a scale.

The resultant line CD will be 9cm.

Hence, line segment CD is thrice the length of AB, 9cm.
