Question

Construct the angle 75 and verify the measure using a
0
protractor.

Answer 1

Step 1: A ray OA is drawn.

Step 2: An arc is drawn with O as a centre.

Step 3: With the same length OA construct an arc from A to B and join OB∴∠AOB=60°

Step 4: With the same length AB construct another arc from B

Step 5: Construct a perpendicular bisector to another arc which is D.Join OD

∴∠AOD=90°

Step 6: Construct a perpendicular bisector to BD= 30/2=15°

Join OC

∴∠AOC=70°

Thus,∠AOC is the required angle making 75°
