Every obtuse angle. There are an infinite number of them.
The sine of an angle is obtained from a right angle triangle. The other two angles are acute, or less than 90 degrees. The sin of the angle is the side opposite the angle divided by the hypotenuse.
The isosceles triangle will have a top angle of 66 degrees and two equal base angles of 57 degrees which all add up to 180 degrees.
An obtuse angleBelow 90o = AcuteAbove 180o = Reflex
The supplementary angle of 57 degrees is 123 degrees The complementary angle of 75 degrees is 15 degrees So: 123 minus 15 = 108 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.
An acute angle is less than 90 degrees, a right angle is exactly 90 degrees, no more or no less, and an obtuse angle is more than 90 degrees but less than 180 degrees. Does that answer your question?
An angle greater than 0 but less than 90 degrees is an acute angle.
An acute angle is an angle measuring less than 90 degrees. An obtuse angle is an angle which is more than 90 degrees, but less than 180. A reflex angle is an angle which measures more than 180 degrees, but less than 360. So an angle of 97 degrees is an obtuse angle.
An angle which is more than 180 degrees but less than 360 degrees is called a reflex angle.
An angle that measures more than 90 degrees but less than 180 degrees is called an "obtuse" angle. Note Angles less than 90 degrees are called "acute" angles. An angle that is exactly 90 degrees is called a "right" angle. Angles that are more than 90 degrees but less than 180 degrees are call "obtuse" angles. An angle that is exactly 180 degrees is called a "straight line". Angles that are more than 180 degrees and less than 360 degrees are called "reflex" angles.
an acute angle
An acute angle
Acute Angle - An angle that is less than 90 degrees. Right Angle - An angle that is exactly 90 degrees. Obtuse Angle - An angle that is more than 90 degrees and less than 180 degrees. There is also: Straight Angle - An angle that is exactly 180 degrees. Reflex Angle - An angle that is more than 180 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".
Obtuse. An acute angle is less than 90 degrees, a right angle is 90 degrees, and an obtuse angle is more than 90 degrees.
The measure of an acute angle is between 0 and 90 degrees (more than 0, less than 90).The measure of an acute angle is between 0 and 90 degrees (more than 0, less than 90).The measure of an acute angle is between 0 and 90 degrees (more than 0, less than 90).The measure of an acute angle is between 0 and 90 degrees (more than 0, less than 90).
