Construct a ΔABC in which BC = 4.5 cm, ∠B = 60° and the sum of the other two sides is 8 cm.
Steps of Construction
1. Draw BC = 4.5 cm
2. Construct ∠CBX=60°
3. Along BX set off BP = 8 cm
4. Join CP.
5. Draw the perpendicular bisector of CP to intersecting BP at A.
6. Join AC.
Therefore, ΔABC is the required triangle.
