Question

Which of the following step (s) is/are incorrect while construcing an angle of 120degree??

Step 1 = Draw a ray A B
Step 2 = With A as centre, draw an arc of any convenient radius which cuts A B at C.
Step 3 = Which C as centre and same radius, draw an arc which cuts the arc draw in Step 2 at point D.
Step 4 = which D as centre and same radius, draw an arc which cuts the arc draw in Step 3 at point E.

Option:-
A. step 3 only
B. step 4 only
C. step 2 only
D. both step 2 and step 3.

Answer 1

Answer:

Option B

Step 4 only

The following occurs correctly instead of step 4.

With D as center and same radius, draw an arc which cuts the arc drawn in step 2 at point E.

After these steps, draw a ray AE. ∠CAE will be equal to 120°.

Thank you. Have a nice day.
