For 45 degrees, move along 100 mm and up 100 mm. For 30 degrees, move along 100 mm and up 58 mm. For 60 degrees move along 100 mm and up 188 mm.

How do you make an angle with horizontal direction?
90 degree
How many angles can we make using ruler and compass?
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.
What does a 22 degree angle and a 68 degree angle make?
Any two angles whose sum is equal to 90 degrees are called "complementary angles".
How many 30 degree angles make a right angle?
10000
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 55 degree angle with using compass and ruler?
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
Can you create a 90 degree angle using a 45 degree angle?
Since 45 degrees is half of 90, you can use two 45s to make a 90.
How do you construct a 30 degree angle without the use of a protactor?
Use a ruler to make a right angle triangle of dimension 3,4,5 the angle adjacent to the side of 4 units length is 30 degrees.
How do you make a 40 degree angle using a ruler and a compass?
With the ruler and compass construct a right angle isosceles triangle with a base of 9 cm At 4 cm from the LHS or RHS of the base draw a line that meets the apex of the triangle The angle of this line will be 40 degrees because each 1 cm of base space represents 10 degrees when joined to the apex
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.

How do you make an angle without a protractor?
You don't always need a protractor to make an angle, just use a normal ruler.
