Construct a quadrilateral ABCD in which AB=1.0cm, angle ABC=120°, angle=60°,BC=7cm and AD=11cm

Answer 1

To construct quadrilateral ABCD, follow the given steps:

Step 1: Draw a line segment AB of length 1.0 cm.

Step 2: At point A, draw an angle of 120 degrees.

Step 3: At point B, draw an angle of 60 degrees.

Step 4: Draw a line segment BC of length 7 cm, starting from point B and making an angle of 60 degrees with AB.

Step 5: Draw a line segment AD of length 11 cm, starting from point A and making an angle of 120 degrees with AB.

Step 6: Let the intersection of line segments AD and BC be point D.

Step 7: The quadrilateral ABCD is now formed, with AB = 1.0 cm, angle ABC = 120 degrees, angle BCD = 60 degrees, BC = 7 cm and AD = 11 cm.
