Construct a triangle

Answer :

Steps of construction:  
1. Draw a line segment BC = 7 cm 
2. With B as centre and with radius 6 cm, draw an arc. 
3. With C as centre and with radius 8 cm, draw another arc, intersecting the previously drawn arc at A. 
4. Join AB and AC. Then,  Δ ABC is the required triangle. 
5. Below BC, make an acute angle ∠ CBX. 
6. Along BX, mark off seven points X1, X2, X3…..X7 such that XX1 = X1X2…… X6X7 
7. Join X7 to C and draw a line through X5 parallel to X7C, intersecting the extended line segment BC at C'. 
8. Draw a line through C' parallel to CA intersecting the line segment BA at A'. Then A'BC' is the required triangle.
