first, using a ruler or compass, mark a point on each of the lines that make the angle so that each point is the same distance away from the vertex as the other. Measure the length of one of the segments as accurately as possible. draw a line connecting each of the marks you made, and measure that segment as well. divide the second measurement by two, and divide it by the first measurement. Using a calculator, find the inverse sine of that result. multiply by two, and you have your angle.

Would Without using a protractor what info would you need to get the measure of an exterior angle?
You would need to know the interior angle because 180-interior angle = exterior angle
What does 35 degrees look like when using a protractor?
When using a protractor, 35 degrees would be measured by aligning the baseline of the protractor with the starting point and then marking the 35-degree angle from there. It would look like an angle that is less than 45 degrees but greater than 30 degrees, as a reference point.
How do you find the size of an angle without using a protractor?
If the angle is a lone, random angle, I believe you would need a protractor to determine the precise size of the angle (in "degrees"). However, you could, in this case, roughly guess as to whether the angle is acute, obtuse, or right (if the little rectangle is shown in the angle). Of course, if an angle is in a position where one can determine its measure using known postulates or theorems, finding the size of this angle becomes much easier. For example, if you know the measure of one angle and you must determine the measure of another angle, but these two angles are vertical angles, or are corresponding angles (by the corresponding angles postulate), you can indeed determine the measure of this angle without a protractor. Additionally, another example is that if you knew a pair of angles were either supplementary angles, complementary angles, or a linear pair, and you were given the measure of one of these angles, you could determine the measure of the other angle without a protractor. Therefore, it depends on the angle you're looking at.
What would you use to measure a angle?
a protractor
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.
How do you measure an acute angle?
You would use a protractor. An acute angle is an angle less than 90°.

Using a protractor will help.
What device or tool would you use to find the size of an angle?
A protractor.
How do you find the vertex of a problem?
Would you mean an angle? Then you'd measure it with a protractor.
How do you find the missing angle measure with parallel lines?
A protractor would be helpful
How do you draw an angle with a protractor?
Figure out which way you want to draw your angle. If you wish to draw the angle to the left, use the bottom row of numbers listed on the top and sides of your protractor and vise versa. Make a mark next to the number of the angle you wish to make (example: a 45 degree angle you would make a mark next to the number 45) then trace the bottom flat edge of the protractor. Using the mark you just made, make a line to connect the mark and the line you drew.
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.
