write definitions of zero angle acute angle right angle obtuse angle straight angle complete angle
Answers
Step-by-step explanation:
An angle with a measure of zero degrees is called a zero angle. If this is hard to visualize, consider two rays that form some angle greater than zero degrees, like the rays in the . Then picture one of the rays rotating toward the other ray until they both lie in the same line.
An acute angle ("acute" meaning "small") is an angle smaller than a right angle. The range of an acute angle is between 0 and 90 degrees.
an angle of 90°, as in a corner of a square, or formed by dividing a circle into quarters
An obtuse angle is more than 90° but less than 180° In other words, it is between a right angle and a straight angle.
an angle of 180° is called straight angle ..
A turn is a unit of plane angle measurement equal to 2π radians, 360 degrees or 400 gradians. A turn is also referred to as a cycle, revolution, complete rotation or full circle. is complete angle..
