Explanation: For cos 270 degrees, the angle 270° lies on the negative y-axis. Thus cos 270° value = 0 Since the cosine function is a periodic function, we can represent cos 270° as, cos 270 degrees = cos (270° + n × 360°), n ∈ Z. ⇒ cos 270° = cos 630° = cos 990°, and so on.

An angle whose measure is equal to 90° is called a right angle. A 180° angle is called a straight angle. Angles such as 270 degrees which are more than 180 but less than 360 degrees are called reflex angles. A 360° angle is called a complete angle. Drawing angles, angle measurement need a protractor.

A 270 degree angle is a reflex angle that measures exactly 270 °. It is formed when two lines or planes intersect each other, and the space between them measures 270 degrees. A 270 degrees angle is a type of reflex angle as reflex angles lie between 180 and 270 degrees. A 270 degrees angle is not an example of an obtuse angle as an obtuse.

An angle is the union of two rays having a common endpoint. The endpoint is called the vertex of the angle, and the two rays are the sides of the angle. The angle in Figure 2.1.2 is formed from → ED and → EF. Angles can be named using a point on each ray and the vertex, such as angle DEF, or in symbol form ∠DEF.

The angle of 270 degrees is an angle that is three times a right angle, i.e., 3 × 90 o = 270 o. We can also write the 270 degrees angle as 270 o, which is also greater than 180 o or a straight line. The 270 degrees angle is an example of a reflexive angle because any angle greater than 180 o is called a reflexive angle. What It Looks Like
