expertss how to draw 45'degree 15degree 30degree 105 degree 75degree 60degree and 45degree with steps of construction

Steps of constructing an angle of 45º are given below.


steps to construct an angle of 30º.

Step 1: Draw a ray AB. Draw an arc of convenient radius, while taking point A as centre. 

Let it intersect the ray AB at C.

Step 2: Taking C as centre and with the same radius as before, draw an arc intersecting the previously drawn arc at D.

Step 3: Join AD. Now, taking C and D as centres, draw arcs with radius more than ½ CD. 

Let these intersect each other at E.

Step 4: Join AE.

Here, ∠ DAE = ∠ BAE = 30º
