Construct a triangle of sides 4 cm, 5 cm and 6 cm and then a triangle similar to it whose sides are of the corresponding sides of the first triangle.

Steps of construction:

i. Now in order to make a triangle, draw a line segment AB = 4 cm.


ii. Then, draw an arc at 5 cm from point A.


iii. From point B, draw an arc at 6 cm in such a way that it intersects the previous arc.


iv. Join the point of intersection from points A and B


v. This gives the required triangle ABC



vi. Now, divide the base in the ratio 2 : 3


vii. Draw a ray AX which is at an acute angle from AB.


viii. Then, plot three points on AX such that; AA1 = A1A2 = A2A3


ix. Join A3 to B.


x. Draw a line from point A2 parallel to A3B and intersects AB at point B’.


xi. Draw a line from point B’ that is parallel to BC intersecting AC at point C’.


Hence, triangle AB’C’ is the required triangle.
