It cant be consyructed you should use protracor, Sorry but can't make 80degree with compass because in compass first cut is 60? You'll then have a 80 degree angle between the lines. It's usually a trick that teachers decide to do on their pupils. 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". Separately draw a 30° angle. Follow the following step to construct 90 Degree Angle 1). Given All Side Lengths To use this method, you should know the length of the triangle’s base and the … 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. 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. Start by drawing a horizontal line and marking the left end “A” and the right end “B” to serve as the vertex of the angle. Draw a point, and a long straight line through it. so the first step isgoing to be to draw a ray which is going to beone of this side of the angle.

I think you have known how the 60 degree can be drawn with compass and ruler. We know that the angles in an equilateral triangleare all 60º in size. It works by constructing an isosceles right triangle, which has interior angles of 45, 45 and 90 degrees. Example 2 : Construct an acute angle of 3 0 °. If you are creating the angles by some techniques, the 10 degree angle can be drawn more accurately than the 80 degree angle can be drawn directly. Thus ∠ YAX = 70 degree. (as shown below) 3). 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. Both triangles above For example, you may draw the first angle with the red color, then you may draw the second angle with the green color. Bisect the 30° angle. Sigh. 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. is 75?.THANKU, U can't draw 80deggree angle with compass, we can draw 221/2 with a compass .Is it divisible by 15, It is possible, Then, place the tip of the compass on “A” and draw an arc through the vertex line. chapter 4 Ex. Spell them properly   ! 80 degree can only be done by a protractor. A 80 degree angle can't be drawn by a compass. Angle trisection allows you to draw lines that divide the right angle into 3 sections, each being 30 degrees each. * Mostly passes. and in between 0?and 60?   *!
