Question

how to construct a quadrilateral if two adjacent sides and three angles are given.​

Answer 1

Answer:

Draw as line segment AB of 5 cm (as shown below)

Step 2: Use protractor and draw angle of 120 degree at vertex A (as shown below):

( you can also draw 120 degree angle with the help of compass. To study how to construct 120 degree angle with the help of compass Click here )

Step 3: Use protractor and draw angle of 110 degree at vertex B (as shown below):

Step 4: Use compass and 3 cm wide open. With B as center, draw an arc with cuts the arm of 110 degree angle; drawn in step 3. And mark point of intersection as C (as shown below)

Step 5: Use protractor and draw angle of 90 degree at point C (as shown below):

( you can also draw 90 degree angle with the help of compass. To study how to construct 90 degree angle with the help of compass Click here )

Step 6: You can observe that arm of 90 degree angle cuts the arm of angle 120 degree angle. Mark point of this intersection as D. And we get resultant Quadrilateral ABCD
