Question
Measure the following angle using a protractor.
- 118°
- 119°
- 117°
- 116°
Hint:
Note the moving line degree read in the protractor.
The correct answer is: 118°
* An angle is formed when two straight lines or rays meet at a common endpoint. The common point of contact is called the vertex of an angle.
* The symbol ∠ represents an angle. Angles are measured in degrees (°) using a protractor.
>>>Given that:
>>>From figure, the protractor reads from 0 degrees to exactly 118 degrees.
>>>Angle measured by protractor becomes 118 degrees.
Step 1:
We line up one ray with 0°. We then read the angle measurement where the other ray crosses the protractor.
Step 2:
Reading from the protractor, the given angle measures 118°.
>>>Therefore, the angle measured is exactly 118 degrees.
