(as shown below) 3). so i've got my original line segment and i've got a copy of the line segment.let's go on to copying an angle. 1. Step 1 : Draw a line ‘l’ and mark a point ‘O’ on it. Share with your friends. See the proof below for more details. we cannot draw this because it is not divisible by 15, it is possible or here we can keep a protector and measure 80 degree and make a cut with compass :). No , 80 degree angle cannot be constructed with compass it can be constructed with protactor. This is the normal 60, With B and C as centres, cut arcs intersecting at L. This is the bisected 60, BUT DO NOT join L to O, instead join L to A. It's not possible as it don't come in the table of 15 . Share 29. its not in 8th standard syllabus . --Click here to visit editor's freeware, shareware page.--. People who are saying that 80 degree angle cannot be constructed with compass they all are a big zero.It is possible and of you want so you can contact me. Think about the geometries involved. The perpendicular rises from A, and passes through where the two arcs intersect. (as shown below) 2). (as shown below) 2). That gives you a 15° angle. You could measure each of the point.

Again use compass and opened to same radius (as of step 10).And with P & Q as center and, draw two arcs which cuts each other at point F. (as shown below) … To draw 80 degree first take a line segment AB.Mark point O on AB.Then keeping compass at O draw a semicircle.Construct 60 degree and a longer 120 degree gradually.Then construct 90°.After that from 90 degree draw another arc on 120 degrees arc.That will be 60 degree.Then keeping compass once on 90 degree and once on new 60 degree draw 2 arcs and let it meet.Join the point with a line and 80 degree is ready.Its very easy. It is not possible because we can draw those angle which are multiple of 15 3 cm. how do i construct a 80 degree angle with a compass...?? My site at Arunet. We can't construct 80? First, draw an angle of 80° say ∠QOA = 180° with the help of protractor. Ex 11.1, 4 Construct the following angles and verify by measuring them by a Protractor : 75° 75° = 60° + 15° 75° = 60° + (30°)/2 So, to we make 75° , we make 60° and then bisector of 30° Steps of construction Draw a ray OA. 80?angles can't be constructed with a compass. The edge of the protractor is labeled with numbers from 0 to 180. Hey guys, the method I will be telling isn't something which can be justified, at least by me. Mark a point O anywhere between P and Q on the line. *! Step 2 : (i) With ‘O’ as center draw an arc of any radius to cut the line at A.
