Solution

Step 1: Constant a triangle ABC as given in the qurstion with AB=4cm, BC=6cm and AC=9cm

Step 2: Draw a ray AX making an acute angle with the base AC and mark 3 points A1,A2,A3 such that AA1=A1A2=A2A3

Step 3: Join A2C and draw a line A3C such that A2C is parallel to A3C where C lie on the produced AC

Step 4: Now draw another line parallel to BC at C such that it meet the produced AB at B

Hence ΔABC is the required triangle similar to ΔABC

The two triangles are not congruent sure all sides and all angles of both the triangle are not equal.
