Construction a quadrilateral ABCD , in which `angleA=65^@ , angleB=105^@ , angleC=75^@ , BC=5.7cm and CD =6.8cm`

Text Solution

Verified by Experts

Steps of Construction:
Step I: Draw BC = 5.7 cm.
Step II: Construct /_XBC= 105° at B and BCY = 105°at C.
Step III: With C as the centre and radius 6. 8 cm, cut off CD = 6.8 cm.Step IV: At D, draw /_CDZ = 115° such that it meets BY at A.The quadrilateral so obtained is the required quadrilateral.
