Question

Draw AB of length 9,4 cm and find its axis of symmetry.
​

Answer 1

Let's first draw a line segment of length 9.4 cm .

1) Draw a line l, mark point A on it.

2) Since length is 9.4 cm, we measure 9.4cm using ruler and compass.

3) Now keeping compass opened the same length, we keep pointed end at point A and draw an arc on line l.

So, the required line segment is AB = 9.4cm .

Now, we need to find its axis of symmetry.

1) Given a line segment AB.

2) Now with A as centre, and radius more than half AB, draw an arc on top and bottom of AB.

3) Now with B as centre, and same radius, draw an arc on top and bottom of AB.

4) Where the two arcs intersect above AB is point C and where the two arcs intersect below AB is point D.

Join CD.

CD is the line of symmetry of line segment AB.

use this formula to find the answer
