# how to construct 105 degree angle ?

105 degree angle

## Procedure – What is 105 Degree Angle:

By following this procedure, we can get what is 105 degree angle.

Step 1: First make the reference line.

Step 2: place the needle of the compass on the point O at which the angle to be made.

Step 3: Draw an arc with simple semi circle by taking some radius such that it intersects the reference line at point D.

Step 4: Now place the compass needle at the point D and draw arc on semicircle at point E without changing radius.

Step 5: Again draw the arc on same semi circle at centre of point E by without changing radius that intersect the point F.

Step 6: Now we get point D, E and F with centre at O. Point E and point F correspond to angle 60 degree and 120 degree respectively.

Step 7: Now change the radius in compass, and draw two arcs from point E and F such that they intersect each other at point (B).

Step 8: Join the point O and B. This line gives 90 degree angle ie is angle BOA = 90 degree.

Step 9: Let this line BO intersects semicircular arc at point G.

Step 10: From point G draw an arc and without changing the radius draw another arc from point F such that they intersect each other at point C.

Step 11: Join the point O and C.

Step 12: The line OC which makes an angle of 105 degree with the reference line OA.

These are all the procedure to draw an angle of 105 degree.

105 degree angle
make the refrace line
draw an arc
such that it intersect the reference line at point  D
draw arc point E without changing radius
and intersect point f
D; E ;F at the center of O point E and f correspond to angle 60 degree and 120 degree
join point O and B
and that solve it
