The different types of angle have different types of names. Where the angle is less than 90 radiant is called as acute angle. The acute angle is smaller angle compared with other type of angle such as right angle, obtuse angle, straight angle, reflex angle, and full angle. The angle which is larger is called as reflex angle.
Definition of a Acute Angle
Definition acute angle, an angle which is less then 90 radiant is called as acute angle. Compared to the other types of angle, an acute angle is very smaller that is in between 0-90 radiant. Also that acute triangle are those where all the interior angle are acute.
Definition of an Acute Angle
An angle of less then 90˚ is called as acute angle and it has three angles. An angle which is exactly 90˚ is a right angle but it is not an acute angle, since it is less than 90˚ or between 0˚-90˚.
Acute Angle Definition Math
An angle which measures less than 90˚ or in between 0˚-90˚ is called as acute angle. In other words, acute angle is a positive angle that measures less than 90˚. Simply it is defined as, an angle of less than 90˚.
Geometry Acute Angle
In geometry, an angle is line segments that intersect in the same plane or it is the amount of bend between two lines. The angles are formed by two intersecting rays at the point of intersection or sharing of same end point. The angles are used to measure the turns in between the two arms. The unit of an angle is degree or radiant. In order to measure an angle from a circle that is a two dimensional plane, if the angle measures greater than 0˚ and less than 90˚ is called as acute angle. The acute angle is referred by the alphabets like ABC or DEF.
In above figure angle A is acute which measures greater than 0˚ and less than 90˚. It is formed by the intersection of two rays like AB and AC, which are called as sides of angle or arms. Where the angle is formed is called as vertex. In figure, the angle 1 which is, marked by square sign is called acute angle. Acute angle is smaller than right angle which is exactly equal to 90˚. Similarly the angle 2 is complementary of an angle 1. Complementary angle of an acute angle is also acute as it measures greater than 0˚ and less than 90˚.
