It is possible to construct a 20 degree angle using only Ruler and Compass. I happened to stumble across a method that is highly accurate.
It is posted on my blog. Check the related link
Well, honey, making an 82-degree angle with a compass is as easy as pie. Just start by drawing a straight line with your ruler. Then place the point of your compass on one end of the line and swing an arc that intersects the line. Finally, use your protractor to measure the angle between the two lines, and voila, you've got yourself an 82-degree angle. Easy peasy lemon squeezy!
First draw a 90 degree angle .Than draw a 20 degree angle from that 90 degree angle . Than the rest of the angle will be 90-20=70 .Now bisect the 70 degree angle we will get 70/2=35. Now add the rest of the angle means 35+20 =55 GOT 55 DEGREE ANGLE
Easiest is to use a protractor. Alternative: Draw a 90 degree angle. Bisect the external angle so that it is 45 degrees. Trisect that angle so that the angle adjacent to the 90 degree angle is 15 deg Then 90 + 15 degrees = 105 degrees. Both, bisection and trisection require the use of a compass (and ruler).
False
You cannot, you must use a protractor.
Use a ruler
pad khaoo !!
use trisection method
first draw a ray .
Construct 2 perpendicular lines which will meet at 90 degrees then by bisecting this angle wll give a 45 degree angle
Well, honey, you start by drawing a line with your ruler. Then, you put the point of your compass on one end of the line and draw an arc. Next, you put the point of your compass on where the arc intersects the line and draw another arc. Where those arcs meet is your 32-degree angle. Voila!
To construct a 125-degree angle using a compass and ruler, start by drawing a straight line and marking a point on it (point A). Using the compass, draw an arc centered at point A that intersects the line. Without changing the compass width, place the compass point on one intersection and draw another arc above the line. Repeat this from the other intersection, creating two arcs that intersect. Finally, use a ruler to draw a line from point A through the intersection of the arcs, forming a 125-degree angle with the original line.
To construct a 37.5-degree angle using a ruler and compass, start by drawing a straight line and marking a point A on it. Then, construct a 60-degree angle at point A by drawing an arc from A, marking points B and C where the arc intersects the line, and connecting A to B. Next, bisect the 60-degree angle by placing the compass point on B, drawing an arc that intersects the angle, and marking those intersection points. Finally, draw a line from A through the intersection of the arcs to create a 30-degree angle, then bisect the 30-degree angle to obtain the desired 37.5-degree angle.

To construct a 54-degree angle with a compass, start by drawing a straight line using a ruler. Place the compass on one endpoint of the line and draw an arc that intersects the line. Without changing the compass width, place the compass on the intersection point and draw another arc. Where the two arcs intersect is a point that, when connected to the endpoint of the line, forms a 54-degree angle.
To construct a 130-degree angle in a parallelogram using a ruler and compass, start by drawing a baseline segment ( AB ). Next, use a compass to create an arc from point ( A ) that intersects the baseline at point ( C ), ensuring that the angle ( CAB ) measures 130 degrees. Then, draw a line from point ( A ) through point ( C ). Finally, replicate this angle at point ( B ) to complete the parallelogram, ensuring that opposite angles are equal.
