Q10 - Geometry

Question

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

• $\angle LAS$
  

Step-by-Step Solution

Answer

The angle $\angle \text{LAS}$ appears to be acute.

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.

The 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 $\angle \text{LAS}$ is less than $90°$, therefore, the angle $\angle \text{LAS}$ appears to be acute.
