Answer 2

A triangle ABC is to be constructed such that . This means that the triangle ABC is similar to the triangle ABC with scale factor as

The steps of construction are as follows:

1. Draw a line segment BC = 5 cm.

2. With B as centre and radius = AB = 4 cm, draw an arc.

3. With C as centre and radius = AC = 6 cm, draw another arc, meeting the arc drawn in step 2 at the point A.

4. Join AB and AC to obtain ABC.

5. Below BC, make an acute angle CBX.

6. Along BX mark off three points B1, B2 , B3 such that BB1 = B1B2 = B2B3.

7. Join B3C.

8. From B2, draw B2C || B3C.

9. From C, draw CA || CA, meeting BA at the point A.

Then ABC is the required triangle.
