An acute angle is an angle that measures more than 0º and less than 90º. This means that, if we only consider whole numbers, an acute angle measures between 1º and 89º.Obtuse triangles, for their part, have two acute angles and one obtuse angle.

Acute Angle

But then, what is the acute angle and its equivalence?

Acute angle: It measures less than 90° and more than 0°.
Right angle: It measures 90° and its sides are always perpendicular to each other.
Obtuse angle: Greater than 90° but less than 180°.

Knowing this, what is the definition of an acute angle?

The acute angle is the angle formed from the union of two straight lines that measure less than 90º or π/2 radians. An acute angle is then one that measures less than a right angle. Thus, the lines that form it are not perpendicular.

what is an acute angle example?

For example, acute angles can be found in equilateral triangles since they are precisely characterized by being composed of three acute angles, that is, three angles of less than 60°. … If two angles add up to 90°, then they are both acute angles.
