Again use compass and open it to any convenient radius. (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°. Draw a line, and establish a point on that line as the vertex of the angle you're going to construct. (ii) With the same radius and A as center draw an arc to cut the previous arc at B. The flow of the answer is as follows: 1. First, draw a straight line using a ruler or scale and name it as XY. Now, to construct at 135 degree angle, we will construct the angle bisector of above angle AOB. OK then, to the discussion. 3.Then by keeping the compass on the end of the semi circle with the help of which you made 120 degree angle draw another arc cutting the first arc. To construct an angle, we must need the following mathematical instruments. First, draw an angle of 80° say ∠QOA = 180° with the help of protractor. This question is only an example . Use Ruler and draw a Line segment BC of any convenient length. With center B and radius BC, cut the previous arc at say DD. Ofcourse Protractor is the simplest device to draw an angle of 100 degree , but by using a compass to make an angle of 100 degree , i suggest you as a last resort , make a circle large enough on a paper with a known diameter or a radius along a point , a circle is a round in shape and it allws compass to rotate arond a point by revolving 360 degree , now you make yy … Draw ray OE passing through C and ray OF passing through D Thus, ∠ AOE = 60° and ∠ EOF = 60° Now we bisect ∠ EOF twice 60° → 30° → 15° 6. Step 4:  With the point of the compass still at Q, draw Drawing 90 Degree Angle with Compass has a variety pictures that united to locate out the most recent pictures of Drawing 90 Degree Angle with Compass here, and then you can acquire the pictures through our best drawing 90 degree angle with compass collection. 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. Now use compass and open it to any convenient radius. an arc near T as shown. (i)  With same radius and with âAâ as center draw another arc to cut the previous arc at âBâ. arc of radius PQ that cuts the arc drawn in Step 2 at R. We can construct a 90º angle either by bisecting a straight angle or Swing an arc above and below the line segment. We know that the angles in an equilateral triangle are all 60º in Step 3: Place the point of the compass at Q and draw an arc that passes through P. Let this arc cut the arc drawn in Step … (i)  To construct 90Â° angle, we are going to bisect the straight angle 180Â°. special sizes. And with O as center , draw an arc which cuts line segment OB at X . Step 1:  Draw the arm PA. Extend RQ to S (as shown below) 7).

Step 3:  Place the point of the compass at Q and draw an Can anybody tell me how to make an angle . (ii)  We get the required angle â AOC  =  90Â°. (ii)  We get the required angle â AOC  =  120Â°. Share with your friends. First let us construct 60Â° angle and then bisect it to get 30Â° angle. You should not change this radius at anytime during the process, otherwise the angle will be wrong. 1. Step 2 at R. So, to construct an angle of 30º, first construct a 60º angle and then bisect it. Please read the Terms and Conditions of Use of this This suggests that to construct a 60º angle we need to construct an equilateral triangle as described below. (ii) We get the required angle â AOB = 60Â°. | Home Page | Order Maths Software | About the Series | Maths Software Tutorials | Are you learning some maths lectures? First we draw angle of 90 degrees using protractor. In this videos I have shown you how to construct degree angle using compass and ruler in only minute. (ii) Construct 60Â° (as shown in the above example). And its done in the following steps: 8). Let us name this point as M.Step 2, Draw a ray MN, extending in any direction and of any length. I feel that this might help in improving anyone’s geometrical skills.  X Research source Step 2 : (i) With ‘O’ as center draw an arc of any radius to cut the line at A. (ii)  With âBâ as center draw another arc of same radius to cut the first arc at âCâ. Now, use the the following steps to construct angles of (1)40° 2() 160° (3) 120° 1.Taking O as centre and any radius draw an arc which intersect OA at E and OO at F. 2.Taking E and F as centres and radius more than 1/2 EF draw arcs which intersect each other at P. With A and B as centers and with the radius more than half of AB draw arcs above AB to intersect each other at âCâ. Australian Business Number 53 056 217 611. This will be one of the arms of our angle. construct an equilateral triangle as described below. This suggests that to construct a 60º angle we need to Join OP Thus, ∠ EOP = 30° Now, we bisect ∠ EOP i.e. arc that cuts the arc drawn in Step 2 at R. Steps:. (30°)/2 = 15° 7. Now Angle PQS = 120 degree (as per Angle Sum Property); as shown below: Now, to construct at 150 degree angle, we will construct the angle bisector of above angle PQR. Therefore, to (i) With âAâ as center, draw an arc of radius more than half of AB in the interior of â AOB. How do I draw a 7.5 degree angle with a compass? how to draw angles with a compass. 4) Placing the compass on the point P, draw a circle that cuts the line AB at point Q. With O as a center point, draw an arc of any radius using a compass, from the left of point O to the right of O. Point E and point F correspond to angle 60 degree and 120 degree respectively. (as shown below) 2). On the paper, draw a line segment longer than the ray of a the 90° 90 ° angle you need.
