first draw a line BC = 4.5 cm
then, make an angle of 45° on point B
then, draw a ray BX of 45° and then, mark an arc of AB + BC = 5.6 cm on BX and name the point as D and then join D to C
and draw a perpendicular bisector of DC
and where the bisector intersect BX name that point as A and join AC
Hence your triangle is ready
