Coterminal angles are two angles that have the identical initial and terminal sides. An angle with measure 800 is coterminal with an angle with measure 800 360 = 440, but 440 is still greater than 360, so we subtract 360 again to find another coterminal angle: 440 360 = 80. Watch this video for another example of how to determine positive and negative coterminal angles. The number or revolutions must be large enough to change the sign when adding/subtracting. lessons in math, English, science, history, and more. The vertex is fixed to the origin of the graph and the initial side, where the angle starts opening, runs along the x-axis. Negative coterminal angle: 200.48-360 = 159.52 degrees. Please note that 440 and -280 are just two of an infinite number of possibilities. In order to determine what the math problem is, you will need to look at the given information and find the key details. So a few examples: -3000 + 1*360 = -2640 -3000 + 6*360 = -840 -3000 + 20*360 = 4200 If Praxis Elementary Education: Math CKT (7813) Study Guide North Carolina Foundations of Reading (190): Study Guide North Carolina Foundations of Reading (090): Study Guide General Social Science and Humanities Lessons. In other words, two angles are coterminal when the angles themselves are different, but their sides and vertices are identical.

So, to check whether the angles and are coterminal, check if they agree with a coterminal angles formula: A useful feature is that in trigonometry functions calculations, any two coterminal angles have exactly the same trigonometric values. Subtracting anymore will result in negative angles. All we have to do is change the value of n to find more coterminal measures! 80^{\circ} + 360^{\circ}\times 2 &= 80^{\circ} + 720^{\circ} \\\\ This number is 2. An angle is a figure formed by two rays that have a common endpoint. Their angles are drawn in the standard position in a way that their initial sides will be on the positive x-axis and they will have the same terminal side like 110 and -250.

Coterminal angle of 300300\degree300 (5/35\pi / 35/3): 660660\degree660, 10201020\degree1020, 60-60\degree60, 420-420\degree420. The thing which can sometimes be confusing is the difference between the reference angle and coterminal angles definitions. Remember that they are not the same thing - the reference angle is the angle between the terminal side of the angle and the x-axis, and it's always in the range of [0, 90] (or [0, /2]). Coterminal angle of 180180\degree180 (\pi): 540540\degree540, 900900\degree900, 180-180\degree180, 540-540\degree540. Find the least positive angle [latex]\theta [/latex] that is coterminal with an angle measuring 800, where [latex]0^\circ \le \theta <360^\circ [/latex].
