Geometric Angle Classification: Determine the Angle Type from Visual Diagram

To determine the type of angle, consider this interpretation:

• Step 1: Examine the angle formed by the depicted intersection of two lines in the diagram.
• Step 2: Compare the observed angle with known categories: an acute angle is less than $90^\circ$, an obtuse angle is greater than $90^\circ$ but less than $180^\circ$, and a straight angle is exactly $180^\circ$.
• Step 3: Visually, the angle appears sharp and much less than $90^\circ$, suggesting it is an acute angle.

Therefore, the type of angle in the diagram is Acute.
