Chapter 1: Q8 (page 20)

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

  • 鈭�2

Short Answer

Expert verified

The angle 鈭�2appears to be right angle and its estimated measure is 90掳.

Step by step solution

01

Step 1. Definition of angle

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

02

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

Acute angle is an angle which measures between 0掳to 90掳.

Right angle is an angle which measures 90掳.

Obtuse angle is an angle which measure between 90掳and 180掳.

Straight angle is an angle which measures 180掳.

03

Step 3. Description of step

From the given figure, it can be observed that the angle 鈭�2is equal to 90掳, therefore, the angle鈭�2 appears to be right angle. Hence, the estimated measure of the angle 鈭�2is 90掳.
