1. Construction of angle 105 degree using compass:(Refer fastened image)

Steps:

Draw a line ab and mark point O on it whereby angle is to be drawn.With O as center draw an arc (semicircle) i beg your pardon intersects the line abdominal muscle at points H and I.Keeping the exact same radius as above and H as center, draw an arc i beg your pardon intersects the semicircle at suggest C. Without transforming the radius as above and C as center, attract an arc i beg your pardon intersects the semicircle at point D. (The points C and also D correspond to 60 and 120 degrees angle respectively).Now draw two arcs of same radius maintaining the centers together C and also D respectively which crossing at allude E.Join clues E and also O and also extend it to suggest X.We obtain the angle XOB=90 degree.Join the points O and D and extend the to point Y, so we gain angle YOB=120 degree.Angle YOX=Angle YOB-Angle XOB=120-90=30 degreeNow let’s bisect the angle YOX.Draw 2 arcs of same radius maintaining the centers D and F (point of intersection that EO and also semicircle) which crossing at suggest G. Sign up with GO.We get the angle GOB=105 degree.

Note: us have created angle that 105 degree as amount of 2 angles that 90 and also 15 degrees. Alternately it deserve to be constructed as sum of two angles the 60 and also 45 degrees.

2. Construction of angle 135 degree using compass: (Refer attached image)

Repeat actions 1 to 6 as declared above.Now let’s bisect edge YOA=90 degree. Attract two arcs of exact same radius maintaining the centers F and also G respectively, which crossing at allude H.Join points H and O and extend the to allude Y.We get the edge YOB =135 degree.
