Steps of construction:1. Draw a line segment BC = 7 cm2. 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 thepreviously drawn arc at A.4. Join AB and AC. Then. A ABC is the required triangle.5. Below BC. make an acute angle 4 CBX.6. Along BX, mark off seven points X1,X2, X3....X7 such that XX1 = X1x2......X6X77. Join X7 to C and draw a line through X5 parallel to X7C,intersecting theextended line segment BC at C'.8. Draw a line through C' parallel to CA intersecting the line segment BA atA'.Then ABC is the required triangle.
