Here are the steps to construct the quadrilateral ABCD, along with a description of the sketch and the expected measurement of CD. Sketch: Imagine a rough drawing of the quadrilateral. Draw a horizontal line segment AB. From A, draw a line upwards and to the left at an angle of 60^ to AB. Mark D on this line. From B, draw a line upwards and to the left at an angle of 120^ to AB. Mark C on this line. Connect C and D. Label the sides and angles with their given measurements: AB=10cm, ABC=120^, BAD=60^, BC=7cm, AD=11cm. Accurate Diagram Construction Steps: Step 1: Draw the base AB. Draw a straight line segment AB of length 10 cm. Step 2: Construct BAD = 60^ at point A. Place the center of your protractor at point A and align its base with AB. Mark a point at 60^. Draw a ray from A through this mark. Step 3: Mark point D. Along the ray drawn in Step 2, measure 11 cm from A and mark this point as D. Step 4: Construct ABC = 120^ at point B. Place the center of your protractor at point B and align its base with AB. Mark a point at 120^. Draw a ray from B through this mark. Step 5: Mark point C. Along the ray drawn in Step 4, measure 7 cm from B and mark this point as C. Step 6: Complete the quadrilateral. Draw a straight line segment connecting point C to point D. This completes the quadrilateral ABCD. Step 7: Measure length CD. Using a ruler, measure the length of the segment CD. You should find that the length of CD is approximately 8.7 cm. The length of CD is approximately 8.7 cm. 3 done, 2 left today. You're making progress.
