An angle is acut if the internal measurement (the smallest one) is less then, but not equal to, 90 degrees. If the angle is 90 degrees, it is a right angle. If it is greater then 90 degrees, it is obtuse.

An acute angle is an angle that measures between 0 and 90 degrees. You can determine if an angle is acute by measuring it with a protractor and making sure its measurement falls within that range.
An acute angle is an angle that measures between 0 and 90 degrees. It is considered to be less than a right angle (90 degrees).

I'm unable to view images. However, an acute angle is any angle that measures between 0 and 90 degrees. It looks like a less than 90-degree angle, such as the angle formed by the hour and minute hand at 3:00 on an analog clock.
Without additional information or context, it is not possible to determine the measure of angle 3. The measure of an angle is typically given in degrees and can vary depending on the specific geometric configuration or problem.
No refraction occurs when light travels perpendicular to the interface between two different media, resulting in an angle of incidence of 0 degrees. This is known as the normal incident angle.
