(ii)  We get the required angle â AOC  =  120Â°. These angles must be constructed with help of COMPASS and SCALE i.e. Example 2 : … 4.3 second question - QUADRILATERAL PLAN. (ii)  Mark a point âOâ on a straight line âlâ. 2. Inscription; About; FAQ; Contact of radius PQ to cut the arc drawn in step 5 at T. arc that passes through P.  Let this arc cut the arc drawn in Share 29. its not in 8th standard syllabus . construct a 120º angle, construct a 60º angle and then extend one of its The flow of the answer is as follows: 1. Step 3:  Place the point of the compass at Q and draw an size. In this videos I have shown you how to construct degree angle using compass and ruler in only minute. Often, we apply the following steps. Now use compass and open it to any convenient radius. With center C, and radius BC, draw an arc. Step 2:  Place the point of the compass at P and draw an arc that cuts the arm at Q. Step 7:  Join T to P. The angle APT is 1) Draw a straight line AB. Step 3 : (i) Join OB. Draw a line ‘l’ and mark a point ‘O’ on it. Use ruler and draw a Line segment OB of any convenient length. 90º. 2.Then putting the compass on the ray of 120 degree angle open the compass half and mark an arc. This suggests that to construct a 60º angle we need to Step 4: Now place the compass needle at the point D and draw arc on semicircle at point E without changing radius. I m stuck at many problems which consist of 80°, 85° and 110°. Now use compass and open it to any convenient radius. With center D, and radius BC draw … (i)  To construct 90Â° angle, we are going to bisect the straight angle 180Â°. (i)  With same radius and with âAâ as center draw another arc to cut the previous arc at âBâ. (i)  With âOâ as center draw arcs of any radius to cut the line l at A and B. You should not change this radius at anytime during the process, otherwise the angle will be wrong. Construction of angle 105 degree using compass:(Refer attached image). Draw a line âlâ and mark a point âOâ on it. (ii) With the same radius and with B as center draw an arc to cut the previous one at C. (iv) We get the required angle â AOC  =  30Â°. Now use compass and open it to any convenient radius. (i) With âOâ as center draw an arc of any radius to cut the line at A. 4) Placing the compass on the point P, draw a circle that cuts the line AB at point Q. With âOâ as center draw an arc of any radius to cut the line l at A. | Home Page | Order Maths Software | About the Series | Maths Software Tutorials | Step 1:  Draw the arm PQ. Extend RQ to S (as shown below) 7). Australian Business Number 53 056 217 611. how to draw 110 degree angle with compass and scale ? OK, so I figured out that if this is your question the below is exactly how to do that. Step 3:  Place the point of the compass at Q and draw an (as shown below) 3). With a compass, mark off a convenient distance from the vertex in each direction on the line, establishing two new points on the line. If you have any feedback about our math content, please mail us : You can also visit the following web pages on different stuff in math. Let this point be P. 3) Then take any suitable radius on the compass. First let us construct 60Â° angle and then bisect it to get 30Â° angle. Therefore, to how to draw angles with a compass. Let us name this point as M.Step 2, Draw a ray MN, extending in any direction and of any length.
