Question

construct the following angles using ruler and compass and vertify by measuring them by a protactor 30 degrees ​

Answer 1

Answer: Step 1: A ray OA is drawn.

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

Step 3:With the same length AB construct another arc from B  

Step 4: Construct a perpendicular bisector to another arc which is D.Join OD

∴∠AOC=90  

∘

 

Step 5: Construct a perpendicular bisector from C to another point of the arc .Join OD

Thus,∠AOD is the required angle

Answer 2

Answer:

Step 1: A ray OA is drawn.

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

Step 3:With the same length AB construct another arc from B

Step 4: Construct a perpendicular bisector to another arc which is D.Join OD

∴∠AOC=90

∘

Step 5: Construct a perpendicular bisector from C to another point of the arc .Join OD

∴∠AOD=105

∘

Thus,∠AOD is the required angle making 105
