Use a "three four five" triangle. Having one leg measure exactly three inches, the other leg exactly four inches, and the hypotenuse measure exactly five inches will yield a ninety degree angle. If you are drawing out the triangle, it may be easier to measure a three inch line using a straightedge and then use a compass to find the point of intersection for the other leg and the hypotenuse.

How do you draw a 75 degree angle without a compass?
Use a protractor.
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.
How do you draw 105 degree angle by using compass?
In conjunction with a straight edge and a protractor
What do you use to measure a right angle?
If you absolutely needed to measure an angle to find out its degree measure, you would use a protractor.
How do you measure angles with a protractor?
A protractor is a shape: semi-circle or full circle, that has degrees marked around the edge. Place the marked centre of the protractor on (for example) the corner of two lines forming a right-angle. The bottom line will be zero, while the vertical line will cross the 90 degrees mark of the protractor, so proving that a right-angle is 90 degrees.
How do you find a 30 degree angle without a protractor?
It is easy to draw an equilateral triangle without a protractor. That gives a 60 degree angle. It is then simply a matter of bisecting the 60 degree angle, using an unmarked rule and compass, to get a 30 degree angle.
