Answer:
Acute Angle
In Geometry, it is important to understand acute angle due to its vast applications in other sections of geometry. In this chapter, we will study acute angle. We will focus on acute angle degree as well as properties of acute angles as well. We will also concentrate on acute angle example too.
Acute angle is an angle which is smaller than the right angle. In other words, an acute angle when the angle is less than 90 degrees forms. There is at least one acute angle in the polygons such as triangle, parallelogram, trapezoid, etc. An angle is formed with the two lines or line segments or rays with a common point. It is through a symbol ‘∠’ that an angle is denoted. One needs to make use of the protector to measure an angle in degrees.
Vertex: Vertex of an angle a corner or a point where lines meet is called.
Arms: Arms of an angle denotes the two lines that meet to make an angle.

What is the Acute Angle definition?
An acute angle is an angle which measures less than 90 degrees. This angle proves to be smaller than the right angle, which is equal to 90 degrees. Some of the examples of acute angles are ∠30o, ∠33o, ∠45o, ∠55o ∠60o, ∠75o, etc. We will try to understand this with an example as below:
Look at the figure below
acute angle
The measurement of ∠ABC is 30 degrees, which is less than 90 degrees and hence it is an acute angle.
Answer:
yes you are right
acute angles are less than 90
