Do you measure angles in anything other than degrees?
You can measure angles in degrees. However, The other common measurement for angles is radians. For this measurement, consider the unit circle (a circle of radius 1) whose center is the vertex of the angle in question. Then the angle cuts off an arc of the circle, and the length of that arc is the radian measure of the angle. It is easy to convert between degree measurement and radian measurement. The circumference of the entire circle is 2 ( is about 3.14159), so it follows that 360° equals 2 radians. Hence, 1° equals /180 radians, and 1 radian equals 180/ degrees. Most calculators can be set to use angles measured with either degrees or radians. Be sure you know what mode your calculator is using.
What is one way to find the sum of a quadrangle without using a protractor?
Using the formula: (number of sides -2)*180 = sum of interior angles
Can you still find the interior sum of angles without measuring?
Yes by using the formula: (n-2)*180 = sum of interior angles whereas n is the number of sides of the polygon
The sum of all the angles of a triangle?
The sum of all the interior angles of a triangle is 180 degrees while the sum of the exterior angles is 360. you can calculate for the measurements of the interior angles of a polygon by using the formula S=(n-2)(180) where n is the number of sides
How do you calculate trignometric angle using java?
I assume you want the trigonometric functions. You can use the functions in the Math class. For example, if the variable "x" contains an angle, you can use Math.sin(x), Math.cos(x), etc., and if you want the angle from a sine stored in "y", Math.asin(y), etc. Note that, as in most programming languages, angles must be specified in radians. The Math class also contains functions to convert from degrees to radians, and from radians to degrees.
