How do you find how many degrees a shape is without a protractor?

The degree of an angle can be determined using the tangent function. From one ray of the angle, draw a perpendicular line until it intersects the other ray of the angle. Measure the length of the first ray (A) and the perpendicular line (B) and set as a ratio of B/A. This ratio is equal to the tangent of the angle.

What is a protractor postulate?
a postulate u go by in order to use the protractor. ex: 63 degrees + 55 degrees(use the protractor to find the correct degrees)
How do you find the degrees of the angles of shapes?
Use a protractor or use the formula: (n-2)*180 = sum of degrees whereas 'n' is the number of sides of the shape or polygon
How do you find the angle degrees?
A protractor is nused to measure angles in degrees.
How do you find the angle of a irregular 2D shape?
Use a protractor
What is the formula for finding an angle in a circle graph?
get a protractor, then multiply your decimal by 360 degrees. Then take that number and find it with the protractor.
How do you find an angle in a parallelogram?
With a protractor and the sum of the interior angles are 360 degrees.
How do you find the circumference of a circle without the diameter or radius?
a protractor
How do you figure out the degree of a shape using a protractor?
You can find out the degrees of the angles of shape shape by following these instructions. First you line up the bottom line of the protractor onto a side of a shape. The corner of the shape should be on the tiny dotlike thing in the middle of the bottom line of the protractor. Next, you find out if the angle is obtuse (larger than a right angle), acute (smaller than a right angle), or right. If it's obtuse, you know that it's larger than 90 degrees. You should look at the larger number the other line is pointing at. If it's acute, find you the angle by finding out which number the other line is pointing at. If you think it's a right angle, see if the line's pointing at another number. Otherwise, it's a right angle.
How do you find angle measures without a protractor?
use the sun and silhoutte
How do you find a reflex angle?
A reflex angle is generally larger that 90 degrees. To find an angle if the diagram is in scale use a protractor is not you would use geometry to find that angle unless the shape is regular such as a square we you know that every angle inside a square equals 90 degrees. So its all depends on the situation.
How do you find the angles in a trapezium?
Using a protractor will help and the 4 interior angles must add up to 360 degrees.
How do you find an angle measurement based on the percent?
You can use a protractor to find out. * * * * * Multiply the percentage by 3.6 [100% = 360 degrees so n% = n*360/100 = n*3.6 degrees].
