Construct a circle and divide the circumference into 36 equal arcs
Each arc will represent 10 degrees and 11 of them subtended to the circle's centre will create an obtuse angle of 110 degrees
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
An angle of 65° can not be trisected using a compass and straight edge.
A 10 degree angle cannot be constructed using only a compass and straight edge.
To construct an 82-degree angle using a compass, start by drawing a straight line using a ruler. Then, place the compass needle on one end of the line and draw an arc that intersects the line. Next, place the compass needle on the point where the arc intersects the line and draw another arc. Finally, use a protractor to measure an angle of 82 degrees where the two arcs intersect the line, and draw the angle.
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

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
To construct a 32-degree angle using a ruler and compass, start by drawing a horizontal line segment. Place the compass needle on one endpoint of the line and draw an arc that intersects the line. Without changing the compass width, place the needle on the other endpoint and draw another arc that intersects the first arc. The angle formed by the intersection of these two arcs with the horizontal line will be approximately 32 degrees.
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.
An angle of 65° can not be trisected using a compass and straight edge.
A 10 degree angle cannot be constructed using only a compass and straight edge.
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.
To construct an 82-degree angle using a compass, start by drawing a straight line using a ruler. Then, place the compass needle on one end of the line and draw an arc that intersects the line. Next, place the compass needle on the point where the arc intersects the line and draw another arc. Finally, use a protractor to measure an angle of 82 degrees where the two arcs intersect the line, and draw the angle.
