An angle whose measure greater than 90 but less than 180 is an obtuse angle.
The measure of an angle whose sides overlap is 0 degrees. It is than not an angle, but rather a line.
Acute
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
A right angle is an angle whose measure is exactly 90 degrees. Continuing around the circle, next is the obtuse angle. An obtuse angle is an angle whose measure is in between 90 and 180 degrees. The last major kind of angle is the straight angle. A straight angle is an angle that measures exactly 180 degrees. Thus the name - the two rays form a straight line. A negative angle is also possible. This just means that you go clockwise instead of counterclockwise.SOURCE: http://library.thinkquest.org/2647/geometry/angle/measure.htmthat website also has lots of more information on angles!
An angle whose measure greater than 90 but less than 180 is an obtuse angle.
Acute Angle: An angle whose measure is less than 90 degrees and greater then zero degrees is called an acute angle. Right Angle: An angle whose measure is 90 degrees is called right angle. Obtuse Angle: An angle whose measure is greater than 90 degrees and less than 180 degrees is called obtuse angle. Straight Angle: An angle whose measure is 180 degrees called a straight angle. Reflex Angle: An angle whose measure is greater than 180 degrees and less than 360 degrees is called a reflex angle. Complete Angle: An angle whose measure is 360 degrees is called a complete angle. Zero Angle: If the measure of an angle is zero it is called a zero angle.
An obtuse angle is DEFINED as an angle whose measure is greater than 90 degrees and less than 180 degrees.
Obtuse angle
The measure of an angle whose sides overlap is 0 degrees. It is than not an angle, but rather a line.
this is a acute angle
