1. Not only multiples of 15 but every multiple of 5 is possible to be constructed by compass..though its not extreme accurate every time Now use compass and open it to any convenient radius. And is not multiple of 15 . Step 2 : (i) With ‘O’ as center draw an arc of any radius to cut the line at A. Then here is a video tutorial on drawing 60 degree angle using ruler and compass.After watching the tutorial below you will be able to draw any angle including 60 degree.Go step by step and learn what is the concept behind the construction. is 90? Method 1 of 2: At the End of a Line Segment 1. First, draw an angle of 80° say ∠QOA = 180° with the help of protractor. Menu. This is a small "sidebar" to a page about drawing angles without a protractor. 80 degree angle is not possible as it is not the multiple of 15. If you are trying to draw a parallelogram with a 75º angle, find the line labeled 75, or estimate where the line would be halfway between the 70 mark and the 80 mark. the triangle. how do i construct a 80 degree angle with a compass...?? My site at Arunet. Draw your angle near the 90 degree mark, but just short of it. The perpendicular rises from A, and passes through where the two arcs intersect. Construct an acute angle of 60 °. it is not possible to make 80 degree with conpass ............you have to use a protactor, How do i construct a 80 degree angle with a compass, The angles which can be easily constructed by the help of compass:-, ONLY ?MULTIPLES ?OF ?15 ?DEGREES ?ARE ?POSSIBLE ?TO ?MAKE ?WITH ?A ?COMPASS, Just make it less than 90 degree and it is formed 80 degree angle. Ltd. All rights reserved. It shows you how to draw an 80 degree angle by drawing a 10 degree angle from a "different base, and how to reliably, accurately, construct" that "different base". We can't construct 80? 4.3 second question - QUADRILATERAL PLAN. With O as centre, and any suitable radius, draw an arc intersecting PQ at A and B . Taking centre as B draw an arc with the same radius taken before to cut the previous arc at C. Join O and C and . and in between 0?and 60? Since 80 degree is not divisible by 15 this angle cannot be drawn by compass and a ruler and we can only draw angles that are divisible by 15 so yeah.. no we cant as it is not divisible by 15 as for this we will have to add 25 to 60 degree angle or 10 to 75 degree angle or subtract 5 from 90 degree angle and these all are not possible so it is impossible, it is not constructed by compass because the those are divisible by 15 only those numbers are constructed by compass, It can only be drawn with the help of an protracter, You all are wrong totally it is possible to construct I will tell after somtime. First draw a 90° angle. Printable step-by-step instructions. It can not construct because 80 degree can not formed by a compass, You can only construct the multiple of 15 on with a compass, We will not make 80 degree angle with compass, YOU CONSTRUUCT WITH COMPASS AND PROTECTOR, It is not constructed by compass only those numbers are constructed which are the multiple of 15, It is not possible the protector can only draw the multiples of 15 or between two multiples. 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.
