Question

Draw a horizontal line AB of 5 cm length

o Draw a ray ‘Ax’ from point A at an angle of

110° (using protractor)

o Draw a second ray ‘By’ from point B at an

angle of 70° (using protractor)

o Cut the both these rays with arcs of 4 cm

radius from points A & B respectively

o Mark the left side intersection point as D and

the right side intersection point as C

o Join the points C and D with scale

Now, we have a quadrilateral (i.e. polygon with 4

sides)

• Step-2: Identifying the type of quadrilateral

o Join A to C (what do we call the line segment

AC?)

o Measure angles ∠ACD and

∠CAB (How do

they compare with each other?)

o Measure angles ∠CAD and ∠ACB (How do

they compare with each other?)

∴Line ABCD and line ADBC​
