Construct a quadrilateral ABCD A = 65°, B = 105°, C = 75°, BC = 5.7 cm and CD = 6.8 cm.

We know that the sum of all the angles in a quadrilateral is 360


i.e. A+B+C+D = 360°


D = 115°


Steps of Construction:


Step I: Draw BC = 5.7 cm.



Step II: Construct XBC = 105° and BCY = 75.



Step III: With C as the center 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.
