An infinite number.
It is relatively simple to draw a perpendicular bisector and so you have a 90 degree angle. It is also simple to bisect an angle and so you can make a 45 deg angle and, if you add it to the other side of the 90 deg, a 135 deg angle. Bisect these and you can make 22.5 deg, 67.5 deg, 112.5 deg and 157.5 deg.
You can keep bisecting angles and adding them to either side of the angles that you have already got. In theory, there is no limit to the number of times this process can be repeated - except the lifespan of the universe.

How do you make an angle of 150 degree with a compass?
To construct an angle of 150 degrees using a compass, you would first draw a ray as the initial side of the angle. Then, place the compass on the vertex of the angle and draw an arc that intersects the initial ray at a point. Next, without changing the compass width, place the compass on the intersection point and draw another arc that intersects the previous arc. Finally, draw a ray from the vertex through the point of intersection of the two arcs to create an angle of 150 degrees.
What 2 angles make a right angle?
two supplementary angles * * * * * NO! Supplementary angles sum to 180 degrees = 2 right angles. The correct answer is complementary angles.
What is the a compass in math?
In math a compass is an object used to draw accurate circles and arcs (parts of circles, or curves). In math, a compass is something that makes a circle and it also measures circumference. How to make a circle: A compass either has led in it or you stick a pencil in it, but it depends on what kind of compass it is. If you want to make a big circle, you expand the 2 sides. when you get it to the size you want, you stick it on paper and twirl it around. It may not be a perfect circle but it most likely will be close.
How to make a circle using a compass and a ruler?
To make a circle using a compass and a ruler, first place the compass point on the paper where you want the center of the circle to be. Adjust the compass width to the desired radius of the circle. Keeping the compass width the same, draw a complete circle by rotating the compass around the center point. Use a ruler to ensure the circle is drawn accurately and smoothly.
How do you make a 110 degree angle using a ruler and a compass?
use trisection method
How do you make a twenty degree angle using a ruler and a compass?
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

How do you make zero degree angle with protector or compass?
Use a ruler
How do you make an angle without using compass and protractor?
By drawing regular polygons as for instance a square will have 4 equal right angles and an equilateral triangle will have 3 equal 60 degree angles.
What inventions does Daedalus's nephew make?
Daedalus's nephew (Perdix/Talos) invented a saw (using the spin and teeth of fish) and a compass (the one used to construct angles).
What are the precautions for using a ruler?
Make sure you are using the correct SI unit on the ruler.
How to make a circle by using only ruler and pencil?
There is a hole in the ruler (i.e.) circle just make the circle using that
How you draw a rectangle twelve centimeters around?
Simple. What you do get a ruler and something to get the angles matching up, therefore use the ruler to make a line 12 cm long. get the protracter and get the angles to match up.
How do you make different angles using two strips?
different angles by using two stripe
How do you make 40 degree angle using compass and ruler what is the maths behind it?
Using a protractor rather than a compass is easier as follows:- Draw a straight line of about 8 cm then place a protractor onto the line with zero degrees at the beginning of the line then mark off 40 degrees. Remove the protractor and join the mark to the beginning of the straight line and 'hey presto!' you have constructed a 40 degree acute angle. ---------------------------- It isn't possible to construct a 40 degree angle with only a straightedge and compass. There are well-known constructions for making a 60 degree angle and a 90 degree angle. Building on this, you can make an angle of any multiple of 15 degrees by adding and/or subtracting these angles. If you successively bisect these angles, you get angles of 30, 15, 7.5, 3.75, ... and 45, 22.5, 11.25, ... etc. degrees. Unfortunately there is no way to combine these angles to get exactly 40 degrees. If there were a way to trisect an angle, this would open up many more possibilities. For instance if you trisect a 120 degree angle, you get 40 degrees. In traditional geometrical constructions, you are only allowed to use a ruler and straightedge - a ruler with no marks on it. The Greeks made this rule several centuries BC. For at least 2500 years people have tried to find a way to trisect an angle, but no one has succeeded. If you change the word "straightedge" to "ruler", (all you really need to do is make a pencil mark on the straightedge), then there is a method, but it isn't considered a construction, and it's not really accurate because you have to juggle the position of the ruler until it fits in a certain position.
