Question

Two adjacent sides of a quadrilateral ABCD are
AB = 3.5 cm, BC = 6.5 cm and three angles are
ZA= 75°, ZB=105º and ZC = 120°.​

Answer 1

Procedure to draw a quadrilateral

Procedure to draw a quadrilateral1. Draw a line segment of ab = 3.5 cm

2. Measure angle 60° from point 'a' by using protractor.

2. Measure angle 60° from point 'a' by using protractor.3. According to property of Quadrilateral

2. Measure angle 60° from point 'a' by using protractor.3. According to property of Quadrilateral         

2. Measure angle 60° from point 'a' by using protractor.3. According to property of Quadrilateral                  ∠a + ∠b  + ∠c + ∠d = 360° 

2. Measure angle 60° from point 'a' by using protractor.3. According to property of Quadrilateral                  ∠a + ∠b  + ∠c + ∠d = 360°            60° + ∠b + 120° + 75° = 360° 

2. Measure angle 60° from point 'a' by using protractor.3. According to property of Quadrilateral                  ∠a + ∠b  + ∠c + ∠d = 360°            60° + ∠b + 120° + 75° = 360°                  ∠b = 105°

2. Measure angle 60° from point 'a' by using protractor.3. According to property of Quadrilateral                  ∠a + ∠b  + ∠c + ∠d = 360°            60° + ∠b + 120° + 75° = 360°                  ∠b = 105°4. Measure ∠105° AT point b and draw a line.

2. Measure angle 60° from point 'a' by using protractor.3. According to property of Quadrilateral                  ∠a + ∠b  + ∠c + ∠d = 360°            60° + ∠b + 120° + 75° = 360°                  ∠b = 105°4. Measure ∠105° AT point b and draw a line.5. measure length = 6.5 cm with the help of compass and cut the arc at the line from point 'b'. you will get point 'c'

2. Measure angle 60° from point 'a' by using protractor.3. According to property of Quadrilateral                  ∠a + ∠b  + ∠c + ∠d = 360°            60° + ∠b + 120° + 75° = 360°                  ∠b = 105°4. Measure ∠105° AT point b and draw a line.5. measure length = 6.5 cm with the help of compass and cut the arc at the line from point 'b'. you will get point 'c'6. at point  'c' measure ∠120° and draw a line, which cuts the line drawn from point 'a'.

2. Measure angle 60° from point 'a' by using protractor.3. According to property of Quadrilateral                  ∠a + ∠b  + ∠c + ∠d = 360°            60° + ∠b + 120° + 75° = 360°                  ∠b = 105°4. Measure ∠105° AT point b and draw a line.5. measure length = 6.5 cm with the help of compass and cut the arc at the line from point 'b'. you will get point 'c'6. at point  'c' measure ∠120° and draw a line, which cuts the line drawn from point 'a'.7. measure the angle 'd', you will find that it measures 75°
