An acute angle is defined as one that is less than 900.
Acute < 90°
An acute angle is an angle less than 90°.
An acute angle is greater than 0 but less than 90 degrees
An acute angle by definition, is an angle that measures anywhere from 1º (or less) to 89º as long as it is smaller than a right angle (90º).
An angle that had a measure equal to or less than 89 degrees.
Complementary angles are acute by definition. A 93 degree angle is not acute and can't have a complement.
-- An 'acute triangle' is a triangle in which each of the three interior angles is an acute angle. -- Each of the three interior angles in every equilateral triangle is a 60-degree angle. -- Any angle of less than 90 degrees is an acute angle. -- It sure looks like every equilateral triangle does fit the definition of 'acute triangle'.
Well, if one angle is acute then the other one has to be acute. This is because the definition of complimentary angles is the sum sum of the angles has to add up to 90 degrees. So therefore, the angle has to add up to 90 degrees.
1 acute angle = 1 acute angle
That is an acute angle. An obtuse angle is not acute.
An acute triangle is a triangle with all angles acute (for example, a triangle with angles 64 ,36, and 80). An acute angle is an angle less than 90 degrees. Also, all angles in a triangle MUST sum to 180 degrees.
The definition of an obtuse angle is an angle great than 90 degrees and less than 180 degree (there cannot be any angle in a triangle larger than 180 degrees). The definition of an acute angle is an angle greater than 0 degrees (an angle cannot measure negative or 0 degrees) and less than 90 degrees. By definition you could have an infinite number of acute angles in a given obtuse angle as an acute angle could be infinitely small as long as it is greater than 0
