An acute angle is an angle that measures less than .
Acute angles can appear in triangles, parallelograms, and other geometric shapes where there is an angle less than degrees.
Which of the 4 angles presented in the figure corresponds to the description of the acute angle?
The correct answer is B) 40°
Choose the appropriate triangle according to the following:
Angle B equals 90 degrees.

Choose the appropriate triangle according to the following:
Angle B equals 90 degrees.
Let's note in which of the triangles angle B forms a right angle, meaning an angle of 90 degrees.
In answers C+D, we can see that angle B is smaller than 90 degrees.
In answer A, it is equal to 90 degrees.
If the two adjacent angles are not equal to each other, then one of them is obtuse and the other acute.
The answer is correct because the sum of two acute angles will be less than 180 degrees and the sum of two obtuse angles will be greater than 180 degrees
True
True or false?
An acute angle is smaller than a right angle.
The definition of an acute angle is an angle that is smaller than 90 degrees.
Since an angle that equals 90 degrees is a right angle, the statement is true.
True
True or false?
One of the angles in a rectangle may be an acute angle.
One of the properties of a rectangle is that all its angles are right angles.
Therefore, it is not possible for an angle to be acute, that is, less than 90 degrees.
False
Which figure depicts a right angle?
A right angle is equal to 90 degrees.
In diagrams (a) and (c), we see that the angle symbol is a symbol representing an angle that equals 90 degrees.
What is an angle?
An angle is the opening that occurs between two lines that join from a vertex. Angles can be measured in degrees or radians.
What is the classification of angles according to their measure?
Angles are classified into 6 types according to their measure:
What is an acute angle?
The acute angle is the narrowest angle of all according to its measure. In this case, an acute angle is one that measures less than
Which of the following angles has a measure less than degrees?
A) Angle of
B) Angle of
C) Angle of
Answer: In this case, option C is the angle that corresponds to an angle less than , that is, it is an acute angle.
