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 do you know how big an angle is?
To determine the size of an angle, you can use a protractor, which measures the angle in degrees. You place the center of the protractor at the angle's vertex and align one side with the baseline. Then, you read the measurement on the protractor where the other side intersects the degree markings. Alternatively, angles can also be measured using trigonometric functions if the lengths of the sides are known.

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.
