An acute angle is lower than 90 degrees. An obtuse angle is higher than 90 degrees. But lower than 180 degrees. A right angle is exactly 90 degrees. A straight angle is exactly 180 degrees. A reflex angle is higher than 180 degrees. A Circle is exactly 360 degrees.
An angle less than 90 degrees is an "acute angle". An angle of exactly 90 degrees is a "right angle". An angle more than 90 and less than 180 degrees is an "obtuse angle". An angle of exactly 180 degrees is a "straight angle". An angle of more than 180 degrees is a "reflex angle".
The last major kind of angle is the straight angle. A straight angle is an angle that measures exactly 180 degrees.
The angle with measure more than 0 degrees and less than 90 degrees is an acute angle, the angle with measure 90 degrees is a right angle,the angle with measure more than 90 degrees and less than 180 degrees is an obtuse angle and the angle with measure 180 degrees is a straight angle. Finally, an angle of more than 180 degrees and less than 360 degrees is a reflex angle.
If they're less than 180 degrees, they're obtuse angles. If more than 180 degrees, they're reflex angles. (Exactly 180 degrees is a 'straight' angle.)
An angle whose measure is exactly 180 degrees is a straight angle.
An acute angle is lower than 90 degrees. An obtuse angle is higher than 90 degrees. But lower than 180 degrees. A right angle is exactly 90 degrees. A straight angle is exactly 180 degrees. A reflex angle is higher than 180 degrees. A Circle is exactly 360 degrees.
An angle less than 90 degrees is an "acute angle". An angle of exactly 90 degrees is a "right angle". An angle more than 90 and less than 180 degrees is an "obtuse angle". An angle of exactly 180 degrees is a "straight angle". An angle of more than 180 degrees is a "reflex angle".
An angle with a measure of 180 degrees will look like a straight line with the vertex being a point in the center. Since a complete circle is 360 degrees, opening an angle to 180 degrees traces out exactly half a circle.
When an angle has a measure of 120 degrees, it is an obtuse angle. When an angle is an obtuse angle its measure is between 90 and 180 degrees. That is: 90 degrees < obtuse angle < 180 degrees.
An angle that measures 180 degrees is called a straight angle.
Acute angle is less than 90 degrees. Right angle is exactly 90 degrees. Obtuse angle is greater than 90 degrees, but less than 180 degrees. A straight angle is 180 degrees. We often call an angle that is greater than 180 degrees a reflex angle.
The last major kind of angle is the straight angle. A straight angle is an angle that measures exactly 180 degrees.
Given an angle A whose measure is in the range [0, 180] degrees, the supplementary angle to A is the angle B such that the measure of A + B = 180 degrees.
Types of angles according to measure: 1. Acute angle- angle measure is less than 90 degrees 2. Right angle- angle measure is 90 degrees 3. Obtuse angle- angle measure is more than 90 degrees but less than 180 degrees. 4. Straight angle- angle measure is 180 degrees 5. Reflex angle- angle measure is more than 180 degrees but less than 360 degrees
The angle with measure more than 0 degrees and less than 90 degrees is an acute angle, the angle with measure 90 degrees is a right angle,the angle with measure more than 90 degrees and less than 180 degrees is an obtuse angle and the angle with measure 180 degrees is a straight angle. Finally, an angle of more than 180 degrees and less than 360 degrees is a reflex angle.
If they're less than 180 degrees, they're obtuse angles. If more than 180 degrees, they're reflex angles. (Exactly 180 degrees is a 'straight' angle.)
