Acute
The complement of an acute angle A is the angle 90° - A. The complement of 13° is 77°.
An angle that is 47 degrees would be considered an "acute" angle. This is because its measurements do not exceed 90 degrees. Anything above 90 would be considered an "obtuse" angle.
Less than 90 degrees is an acute angle, a 90 degree angle is a right angle, and an angle greater than 90 degrees is called an obtuse angle.
A chevron. Basically, any polygon with an acute angle whose vertex points to the center of the shape.
an acute angle is an angle whose measure is less than 90.
An acute angle is an angle whose measure is between 0 and 90 degrees.
There is no such thing as an equilateral angle. Equilateral refers to a shape whose sides are of equal length. The lengths of the sides of an angle are indeterminate.
An angle whose degree measure is between 0 and 90 is an acute angle. An angle whose degree measure is between 90 and 180 is an obtuse angle. These are basic properties of geometry.
Acute angle
Acute. 0 < acute < 90 < obtuse < 180 < reflex < 360
an acute angle
this is a acute angle
An acute angle
A complement of an acute angle must be an acute angle. An acute angle is an angle whose measure is more than 0 degrees but less than 90 degrees. For example, even if the angle was the minimum 1 degree, the complement is still 89 degrees, which is still acute. Therefore, any combination of a complement of an acute angle MUST be acute.
Acute
An acute angle is an angle measured less than 90o.
