An obtuse angle is one measuring between 91 and 180 degrees. This person is wrong an obtuse angle is between 91 and 179 degrees, if it was 180 degrees then it would be a srtaight angle.
A right triangle is a triangle that contains a 90 degree angle, an obtuse triangle contains an angle that is from 91 degrees to 179 degrees.
A straight angle (180 degrees) makes a perfectly straight line. Any degree below 180 degrees (0-179 degrees) is NOT a straight angle NOR a straight line. straight angle = 180 degrees straight angle = straight line 180 degrees
91 - 179.
179 degrees
An obtuse angle
It is a 1 degree angle
A supplementary angle will add up to 180 degrees so to find the supplementary angle of 179 degrees, you would take 180-179 to get a 1 degree angle.
179 degrees
Straight angle, which is 180 degree, obtuse angle, which is 179 degree to 91 degree, right angle, which is 90 degree, and acute angle, which is 89 degree to 1 degree.
Using a protractor will help.
It is an acute angle. All angles from 1 - 89 degrees are acute. A 90 degree angle is a right angle. Angles from 91 - 179 are obtuse angles.
An angle can have up to 180 degree's. A circle can have up to 360 degrees. An angle with 180 degrees is a straight line. If you went any farther than it would change into a 179 degree angle, and so on.

Since the sum of measures of the two supplementary angles is 180⁰, we have:180⁰ - 165⁰12' = 179⁰60' - 165⁰12' = (179 - 165)⁰(60 - 12)' = 14⁰48'
An obtuse angle is a measurement of 91 degrees to 179 degrees. If it is 90 degrees, it is a right angle. If it is 1 degree to 89 degrees it is an acute. If it is 180 degrees it is a straight angle.
An obtuse angle is one measuring between 91 and 180 degrees. This person is wrong an obtuse angle is between 91 and 179 degrees, if it was 180 degrees then it would be a srtaight angle.
