Chapter 1: Q13 (page 21)

State whether the angle appears to be acute, right, obtuse, or straight.
$∠ L T S$

Short Answer

Expert verified

The angle $∠ L T S$ appears to be the straight angle.

Step by step solution

Step 1. Definition of angle.

An angle represented by a symbol $∠$ 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 $∠ L T S$ measures exactly $180 °$ , therefore, the angle $∠ L T S$ appears to be the straight angle.
