 Hello and how are you all today? The question says construct the angles of the following measurement. Now here we need to draw the angle of 30 degree. I have already written down the steps of construction and I will be drawing it for you simultaneously. The first step is to draw a ray OA like this. Now the second step is with its initial point O as the center and any radius draw an arc. Cutting OA at C. So what we need to do is we need to take O as the center and any convenient radius. We need to draw an arc like this which is intersecting OA at point C. Now with C as the center and same radius intersect this previous arc at point D. This is our next step of construction that is with center C and same radius that was in step 2. Draw an arc cutting the arc of step 2 in D. Then now with CD as centers and radius more than half of CD draw two arcs intersecting at B. So we will be taking C and D one by one as center and the radius should be more than half of CD. We need to draw one arc with C and then one arc with D intersecting at point B. Now the next step is to join OB. Now this angle that is AOB is the required 30 degrees angle. So the last and final step is to join OB and then angle AOB is the required 30 degrees angle. So this was our required construction 30 degrees. So this completes my entire question. Hope you enjoyed and take care.
