Final Answer:
In geometry, angles are classified based on their measure. Acute angles are those that measure less than 90 degrees, and both ∠1 and ∠7 fall within this range.
Therefore, the correct answer is A) Acute angles.
Step-by-step explanation:
Angles are measured in degrees, and their classification provides insights into their size and relationship with other angles. Acute angles are defined as angles that measure less than 90 degrees. In the given options, ∠1 and ∠7 both fall into this category because they are smaller than 90 degrees.
Acute angles are commonly found in various geometric shapes, such as triangles and quadrilaterals, and they play a crucial role in understanding the properties of these shapes. In the context of ∠1 and ∠7, their acute nature indicates that they are smaller than a right angle and contribute to the overall geometry of the figure under consideration.
Acute angles play a fundamental role in geometry, influencing the properties of different shapes and their relationships. Understanding the characteristics of acute angles is essential in solving geometric problems and analyzing various configurations of shapes.
Therefore, the correct answer is A) Acute angles.
