Chapter 1: Q7 (page 20)

State whether the angle appears to be acute, right, obtuse, or straight. Then estimate its measure.
$∠ 1$

Short Answer

Expert verified

The angle $∠ 1$ appears to be acute.

Step by step solution

Step 1. Definition of angle

An angle represented by symbol $∠$ is the figure formed by two rays that have the same end point.

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 $∠ 1$ is less than $90 °$ , therefore, the angle $∠ 1$ appears to be acute.
