To find angle measures without a protractor, you can use geometric principles and tools like a compass and straightedge. For instance, you can create congruent angles by copying an angle using a compass, or use the properties of triangles, such as the fact that the sum of the interior angles in a triangle is always 180 degrees. Additionally, you can apply trigonometric ratios in right triangles if you have side lengths available.

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.
How can you find right angles without using a protractor?
You can never really be certain about the measure of an angle without using a protractor, or some similar tool. Usually, you can try to "eyeball" it, though. Just remember that a right angle is the same as an angle in a square. It is also a quarter of a whole revolution.

How can I accurately measure angles using a protractor?
To accurately measure angles using a protractor, place the center of the protractor on the vertex of the angle. Align one side of the angle with the zero line on the protractor. Read the measurement where the other side of the angle intersects the protractor scale.

How do you measure a reflex angel with 180 protractor?
To measure a reflex angle using a 180-degree protractor, first position the protractor so that its baseline aligns with one side of the angle, ensuring the center point is at the vertex. Measure the smaller angle formed on the protractor, which will be less than 180 degrees. Subtract this measurement from 360 degrees to find the reflex angle. For example, if the smaller angle measures 120 degrees, the reflex angle would be 360 - 120 = 240 degrees.
