Question

State whether the angle appears to be acute, right, obtuse, or straight.

• $\angle 2$
  

Short answer

The angle $\angle 2$appears to be acute.

Step-by-step solution

Step 1. Definition of angle.

An angle represented by a symbol$\angle$ is the figure formed by two rays that have the same endpoint.

Step 2. Apply the definition of acute angle, right angle, obtuse angle and straight angle

Acute angle is an angle which measures between $0°$to $90°$.

Right angle is an angle which measures $90°$.

Obtuse angle is an angle which measure between $90°$and $180°$.

Straight angle is an angle which measures $180°$.

Step 3. Description of step.

From the given figure, it can be observed that the angle $\angle 2$is less than $90°$, therefore, the angle $\angle 2$appears to be acute.
