Question

Draw a linear pair of angles

Answer 1

⇒Steps of construction

STEP 1: Draw a linear pair of angles and label them as ABD and DBC.

STEP 2: Draw an arc of sufficient radius, intersecting the ray BA, ray BD and the

ray BC at points G,H and I respectively.

STEP 3: With centre, I and radius greater than half of HI draw an arc inside of DBC.

STEP 4: With centre G and the same radius draw an arc inside of ABD.

STEP 5: With centre H and the same radius, draw two arcs one on each side of the ray BD and intersecting the arc drawn in STEP 3 at F and the arc drawn in STEP 4 at E.

STEP 6: Draw the ray BE and the ray BF.

After the measurement, it can be verified that EBF is a right angle.

Hence the ray BE and the ray BF are perpendicular to each other.
