What is the relationship between an acute angle and a right angle?

The correct answer states that an acute angle is less than a right angle. To understand this relationship, it's essential to define each type of angle. An acute angle is defined as an angle that measures less than 90 degrees, while a right angle measures exactly 90 degrees.

Since acute angles fall within the range of 0 degrees to just below 90 degrees, they are inherently smaller than right angles. This distinction is crucial in geometry, as it helps in classifying angles based on their measures and understanding their properties in various contexts, such as in shapes and figures.

Understanding this relationship allows one to categorize angles accurately and use that knowledge for solving problems related to angle measurement and construction in geometry.
