Question

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

• $\angle LTS$
  

Short answer

The angle $\angle LTS$appears to be the straight angle.

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.

An acute angle is an angle that measures between $0°$to $90°$.

The right angle is an angle that measures $90°$.

An obtuse angle is an angle that measures between $90°$and $180°$.

A straight angle is an angle that measures $180°$.

Step 3. Description of step.

From the given figure, it can be observed that the angle $\angle LTS$measures exactly $180°$, therefore, the angle $\angle LTS$appears to be the straight angle.
